Summary:
Implemented a version of accessibility Hints on android by adding hint text to the end of contentDescription. There is already an existing prop on js and iOS implementation.
Changes involve:
* adding a prop on native android code for accessibilityHints
* setting the accessibilityDelegate after the props are all loaded.
* Instead of directly updating the accessibility delegate, the prop setters now update state by setting the values of the variables. Once all props are set, the accessibility delegate is set based on the props
* BaseViewManager keeps track of whether or not accessibility props have been set
* AccessibilityDelegateUtil keeps track of what the props have been set to. (Renamed AccessibilityRoleUtil to AccessibilityDelegateUtil)
Currently, this is the easiest way of emulating the way accessibility hints work on iOS, and I think having an android counter part is better than having nothing.
It's different from iOS in that it will announce the hint before the role, and also cannot be turned off.
Ex:
if I set the accessibility like this:
```
<View
style={styles.container}
accessible={true}
accessibilityLabel="accessibility label"
accessibilityRole="button"
accessibilityStates={['selected']}
accessibilityHint="accessibility Hint">
<Text> Tester </Text>
</View>
```
Talk back will read:
`accessibility label, accessibility Hint, button, selected`
In the future for next steps, I plan on investigating the process of making a second announcement after the first

Added a check for null on `accessibilityStates`.
Now, if a null value is passed in to the prop, it simply does not do anything.

Summary:
Context:
After discussing with @[1038750002:yungsters], `currentViewStates` is a very ambiguous name for a prop, especially because there are only two possible values. From a developer's perspective, it makes more sense to just call them `accessibilityStates` because the main use for them is to add states to Talkback and Voiceover.
Defense for changing name in Android: The actual implementation of what we're changing under the hood in Native Code is abstracted away from developers using React Native, so as long as behavior is as they would expect, it makes more sense to change the name into a clear one regardless of how it is implemented.
Changes:
changed the Prop name from `currentViewStates` to `accessibilityStates` in the BaseViewManager file where the view property is being exposed.

Summary:
Added native android support for the prop accessibilityStates.
If 'selected' is passed in, it calls view.setSelected(true)
If 'disabled' is passed in, it calls view.setEnabled(false)
If both are passed in, both are set on the view.

Summary:
Added a new property to View for Accessibility called `accessibilityRole`. This property merges functionality of existing properties: `accessibilityTraits` (iOS) and `accessibilityComponentType` (android).
Currently, nine values are supported with equivalent behavior as `accessibilityTraits` (iOS) when `accessibilityRole` is set on iOS Voiceover and Android TalkBack
```
| 'none'
| 'button'
| 'link'
| 'search'
| 'image'
| 'keyboardkey'
| 'text'
| 'adjustable'
| 'tabbar'
```
They currently support similar behavior on talkback on Android and voice over on iOS
Does not break functionality of existing properties, but have not tested for behavior of setting both this one and the old one.
* iOS - I added a property accessibilityRoles, and basically remapped it to the same thing as accessibilityTraits. I also added in enum mappings for keyboardkey and tabbar.
* Android - Also added a property accessibilityRoles, from the Android side. For the underlying native functionality, I built a helper class that is based off of AccessibilityRolesUtil.java from the accessibility team. Biggest changes made are that I defined my own enums if needed, and also set some properties to match the functionality of iOS Accessibility Traits. I also handled the logic for switch/case statements of setting roles for the android side on this file. Also, I currently haven't localized strings for setRoleDescription, but plan to.
* Javascript - I added a view property accessibilityRoles in ViewPropTypes.

Summary:
If the z-index was updated after the initial mount, changes would not be reflected because we did not recalculate the z-index mapped child views and redraw the view. This adds code to do that and call it whenever we update z-index.
**Test plan**
Tested by reproducing the bug with 2 overlapping views that change z-index every second. Made sure it now works properly and z-index changes are reflected.

Summary:
This is the better fix for the same issue as mentioned in PR https://github.com/facebook/react-native/pull/14560
Certain rotateX, rotateY, scaleX and scaleY animations do not work correctly on some phones in Android 7.0.0, causing issues such as https://github.com/facebook/react-native/issues/14462 and https://github.com/facebook/react-native/issues/13522.
The issue can be fixed on JS side by setting an additional transform for perspective, eg. `{perspective: 1}` which triggers a `setCameraDistance` call in native code.
The fix in this PR always sets the camera distance on transforms, even when no perspective transform was specified. The default camera distance is set before the scale multiplication, to make sure that the value is appropriate for the phones density. The value calculates to an Android 'default' camera distance of 1280 * scale multiplier; https://developer.android.com/reference/android/view/View.html#setCameraDistance(float)
If a perspective transform is specified, this value will be used correctly still.
This fix was tested on the RNTester. Before the fix, on some devices, the FlatList example, with inverted turned on, will not display the list.
Devices that have been confirmed to have this issue:
FRD-AL10（honor 8） EMUI:5.0 android: 7.0
MHA-AL00(Mate9) EMUI:5.0 android:7.0
Huawei P10 VTR-L09, running Android 7.0
After the fix, the inverted FlatList displays correctly.

Summary:
This adds support for sticky headers on Android. The implementation if based primarily on the iOS one (https://github.com/facebook/react-native/blob/master/React/Views/RCTScrollView.m#L272) and adds some stuff that was missing to be able to handle z-index, view clipping, view hierarchy optimization and touch handling properly.
Some notable changes:
- Add `ChildDrawingOrderDelegate` interface to allow changing the `ViewGroup` drawing order using `ViewGroup#getChildDrawingOrder`. This is used to change the content view drawing order to make sure headers are drawn over the other cells. Right now I'm only reversing the drawing order as drawing only the header views last added a lot of complexity especially because of view clipping and I don't think it should cause issues.
- Add `collapsableChildren` prop that works like `collapsable` but applies to every child of the view. This is needed to be able to reference sticky headers by their indices otherwise some subviews can get optimized out and break indexes.

Summary:
In #7916 I moved transform matrix decomposition logic from JS to java. The next step is to accept list of transforms instead oftransform matrix as a transform ReactProp. This way there is no extra processing required on JS side for the transform param (at least for android now) and this on the other hand allow us to execute transform updates (through offloaded animation) solely on the UI thread.
After this change there is a whole bunch of stuff from `Libraries/Utilities/MatrixMath.js` that can be deleted (methods like: determinant, inverse, transpose). Although astreet mentioned under one of my previous commits that the code is still being referenced internally at fb, so I decided not to delete it here.

Summary:
This diff translates implementation of transform matrix decomposition from JS to java. This is to support offloading animations of transform property, in which case it is required that we can calculate decomposed transform in the UI thread.
Since the matrix decomposition code is not being used for other platform I went ahead and deleted parts that are no longer being used.

Summary:
transformMatrix only worked on iOS and there is an equivalent API that (mostly)
works cross platform.
decomposedMatrix could technically be passed on Android but it wasn't document and explicitly flagged as not working.
My goal is to deprecate both uses and then the only supported API is the `transform: [{ matrix: ... }]` form.
The only difference is that on Android the matrix gets decomposed.
Currently there is some special cased magic that renames transform -> transformMatrix or decomposedMatrix depending on platform.
https://github.com/facebook/react/blob/master/src/renderers/native/ReactNative/ReactNativeAttributePayload.js#L50
Therefore I'm adding an alias for both native platforms called just "transform".
Next I'll swap over the JS to always target the name "transform". The only difference is how the value is marshalled over the bridge in processTransform.
To do this, I have to clean up a few callers. Mostly that's just swapping to the new API.
For buildInterpolator this is a bit trickier but this fixes it for all our use cases (which is only the Navigator in AdsManager).
