Summary:
Fix#23849. When setting a semi-transparent background on text, it becomes obvious that we are drawing the background color twice. Since background color is handled by the view, we should not need to draw the glyph background color too.

Summary:
This PR implements the first part of [RFC0004: CocoaPods Support Improvements](353d44f649/proposals/0004-cocoapods-support-improvements.md), splitting the `React.podspec` into separate podspecs to more closely match the structure of Xcode projects.
The new structure aims to have one to one mapping between Xcode projects and podspecs. The only places where we differ from this mapping are:
* `React/React-DevSupport.podspec`: `DevSupport` is a part of `React.xcodeproj`, which corresponds to the `React-Core` pod. However, we can't include it in the `React-Core` pod because `DevSupport` depends on `React-RCTWebSocket`, which depends on `React-Core`. Pods may not have circular dependencies.
* The new pods under `ReactCommon/` don't have a corresponding `xcodeproj` because there are no `xcodproj` files in `ReactCommon/`. Those C++ modules are included in `React.xcodeproj`.
*Next steps (not in scope of this PR):*
- Start submitting the Podspecs to CocoaPods on a deploy (or turn the React Native repo into a spec repo): this is important in order to make the experience nicer for library consumers, so that it's not necessary to specify the local path of each Podspec in `Podfile`, you can just add `pod 'React', <version>`.
- Add `Podfile` to the default project template (I have a PR ready for this, but because of bugs related to subspecs, it's blocked on this PR)

2.Quickly press the keyboard with multiple fingers
```
// RCTBaseTextInputView.m
……
if (_maxLength) {
NSUInteger allowedLength = _maxLength.integerValue - backedTextInputView.attributedText.string.length + range.length;
if (text.length > allowedLength) {
……
```
when value's length > maxLength,the allowedLength not a negative number.it was transformed into a big number,because it is type NSUInteger.so the `text.length > allowedLength` always false.

Summary:
iOS-specific.
For languages with complex input (such as Japanese or Chinese), a user has to type multiple characters that are then merged into a single one.
If `-[UITextView setAttributedString:]` is used while the user is still typing, it resets the input and characters are not being treated as typed together.
This PR avoids calling this method if possible, replacing it by just copying the attributes if the string has not been changed. That preserves the state and user can continue to type Korean or Chinese characters.

Essentially, the steps to reproduce are described in [the issue](https://github.com/facebook/react-native/issues/19339):
1. Type some Korean characters in TextInput, such as "하늘" (buttons `ㅎ`,`ㅏ`,`ㄴ`,`ㅡ`,`ㄹ`).
2. Then move the cursor to the beginning of the text, type "파란" (buttons `ㅍ`,`ㅏ`,`ㄹ`,`ㅏ`,`ㄴ`) this time.
**Behaviour before this fix (broken)**
Actual text: `ㅍㅏㄹㅏㄴ하늘`.
Expected text: `파란하늘`.
Characters aren't combined properly.

**Behaviour after this fix (correct)**
Actual text: `파란하늘`.
Expected text: `파란하늘`.
Characters are combined, the same behaviour is in vanilla iOS `UITextView`.

Summary:
If text is truncated and an inline view appears after the truncation point, the user should not see the inline view. Instead, we have a bug such that the inline view is always visible at the end of the visible text.
This commit fixes this by marking the inline view as hidden if it appears after the truncation point.
This appears to be a regression. React Native used to have logic similar to what this commit is adding: 1e2a924ba6/Libraries/Text/RCTShadowText.m (L186-L192)
**Before fix**
Inline view (blue square) is visible even though it appears after the truncation point:

The full text being rendered was:
```
<Text numberOfLines={1}>
Lorem ipsum dolor sit amet, consectetur adipiscing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna
<View style={{width: 50, height: 50, backgroundColor: 'steelblue'}} />
</Text>
```
**After fix**
Inline view is properly truncated:

**Test Plan**
Tested that the inline view is hidden if it appears after the truncation point when `numberOfLines` is 1 and 2. Similarly, verified that the inline view is visible if it appears before the truncation point.

Summary:
If a view inside of an inline view became dirty (e.g. its top/left prop changed), its position would not update on screen. This is because Yoga didn't know the view needed to be relaid out because Yoga's dirty signal didn't propagate all the way up to the root.
The problem is that inline views don't have a parent in the Yoga tree causing Yoga's dirtiness signal propagation to get cut off early. The fix is, when an inline views gets dirty, mark the parent Text's Yoga node as dirty. This will cause Yoga's dirtiness signal to propagate all the way up to the root node.
Yoga has a hook to inform you when your node is marked as dirty: `YGNodeSetDirtiedFunc`. We leverage this to find out when an inline view's Yoga node gets dirtied.
React Native almost handled this case. Everything worked fine as long as the inline view was nested inside of a virtual text node like this:
```
<Text>
<Text>
<InlineView />
</Text>
</Text>
```
However, the bug repros when the inline view is nested in a non-virtual text node:
```
<Text>
<InlineView />
</Text>
```
The fix is to move the special dirtiness propagation logic from `RCTVirtualTextShadowView` to `RCTBaseTextShadowView`.
**Test Plan**
Created an inline view. Tested the following kinds of updates on the inline view's content:
- Moved the content
- Removed the content
- Added the content
Tested this for an inline view that is directly inside of a text node as well as one that is nested under a virtual text node.
Here's the code I used for the inline view that moved its content after 2 seconds:
```
const RN = require('react-native');
const React = require('react');
export default class InlineView extends React.Component {
constructor(props, context) {
super(props, context);
this.state = { posBottom: false };
}
componentDidMount() {
super.componentDidMount && super.componentDidMount();
setTimeout(() => { this.setState({ posBottom: true }); }, 2000);
}
render() {
const pos = this.state.posBottom ? 25 : 0;
const color = this.state.posBottom ? 'pink' : 'green';
return (
<RN.View style={{ width: 50, height: 50, backgroundColor: 'steelblue'}}>
<RN.View style={{ width: 25, height: 25, top: pos, left: pos, backgroundColor: color }} />
</RN.View>
);
}
}
```

Summary:
1. The user inserts a character ('0') at index 0. Because the range matches 0, 0, predictedText is set to that character that was inserted.
2. In textInputDidChange, it discovers a mismatch between the rendered text ('1234') and predicted text ('0')
3. This triggers textInputShouldChangeTextInRange to be called again with the 'new' text that it thinks was just added ('1234')
4. It goes to insert this text, but runs into the maxLength limit, so it gets truncated and then inserted.
(I'm not totally sure why only happens if maxLength is set - I need to look into that.)
One fix for this is to just get rid of the range check, but that'll regress #18374. I decided to just check and see if the rendered text is empty instead of checking the range where text could be inserted, since that seems like it should properly handle both cases.

Summary:
This fixes#19193
Characters of different languages may have different height and different baseline, even with a same font and same font-size. When they mixed together, iOS will adjust their baselines automatically, to display a suitable view of text.
The problem is the behavior of dealing with the text-style property 'lineHeight'.
It once to be a right way at version 0.52.3, to setting a base-line-offset attribute for the whole range of the string. However, in current version, it enumerated the string, and set a different base-line-offset for different font-height characters.
And this behavior broke the baseline adjustment made by the iOS. It just make every character's baseline aligned to a same line. But it is not supposed to displaying characters of different languages like that. Chinese characters' baseline is the bottom of each, however, it is not for English characters.
So maybe it is the better way to give a same value of base-line-offset attribute for the whole string. And this PR just did that: found the biggest value of font-height in the text, and calculate the offset with that biggest value, then set to the whole string. This will keep the origin baseline adjustment for different languages' chars made by iOS.
Since I always got an error when running the snapshot test locally, I can't even pass the them with the unmodified code in master branch.
The error is "Nesting of \<View\> within \<Text\> is not currently supported."
After I comment all of the check of that error from the source code, I got a different snapshot from the reference ones. It seems that all components which will cause that error are not rendered in the reference images.
Since this PR changed the behavior of 'lineHeight' property, it's better to add a new snapshot case for the situation of different-language-characters' mixture. So maybe somebody could help me with that or maybe it should be a issue?

The version of `nullthrows` in `fbjs` is outdated and already missing features that exist in the standalone `nullthrows` package.
Also, this mitigates the inevitable collision between `nullthrows` (as a Haste module) and `nullthrows` (as a `node_modules` dependency).

Summary:
**Motivation**
Whenever a user changes the system font size to its maximum allowable setting, React Native apps that allow font scaling can become unusable because the text gets too big. Experimenting with a native app like iMessage on iOS, the font size used for non-body text (e.g. header, navigational elements) is capped while the body text (e.g. text in the message bubbles) is allowed to grow.
This PR introduces a new prop on `<Text>` and `<TextInput>` called `maxFontSizeMultiplier`. This enables devs to set the maximum allowed text scale factor on a Text/TextInput. The default is 0 which means no limit.
Another PR will add this feature to Android.
**Test Plan**
I created a test app which utilizes all categories of values of `maxFontSizeMultiplier`:
- `undefined`: inherit from parent
- `0`: no limit
- `1`, `1.2`: fixed limits
I tried this with `Text`, `TextInput` with `value`, and `TextInput` with children. For `Text`, I also verified that nesting works properly (if a child `Text` doesn't specify `maxFontSizeMultiplier`, it inherits it from its parent).
Lastly, we've been using a version of this in Skype for several months.
**Release Notes**
[GENERAL] [ENHANCEMENT] [Text/TextInput] - Added maxFontSizeMultiplier prop to prevent some text from getting unusably large as user increases OS's font scale setting (iOS)
