Summary:
Would like feedback from the community as this may not be the best solution for all
I would like to restrict (or paginate) the fling of a horizontal ScrollView when `snapToInterval` is set. This is not currently possible with `pagingEnabled`, since the pagination works only when items are the entire width of the ScrollView.
This implementation simply restricts the predicted `targetOffset` found from the `x` velocity and replaces it with the offset when the pan gesture ended.
To get pagination working, I may paginate based on the interval by calculating the offset delta from the beginning of the gesture to current offset and restricting the scrolling behavior to the `snapToInterval`. If this is preferred, I can update this PR or make a new one, but wanted to start a discussion since it seems like there are many in the community that would like this feature #21302 .
[General] [Added] - add prop `disableIntervalMomentum` to disable the predictive scrolling behavior of horizontal ScrollViews

Summary:
For a small subset of Android devices, the following line of code caused the device to crash
```
output.transferFrom(input, 0, Long.MAX_VALUE);
```
According to the [Java docs](https://docs.oracle.com/javase/1.5.0/docs/api/java/nio/channels/FileChannel.html), this is what the function does.
> Transfers bytes into this channel's file from the given readable byte channel.
An attempt is made to read up to count bytes from the source channel and write them to this channel's file starting at the given position. An invocation of this method may or may not transfer all of the requested bytes; whether or not it does so depends upon the natures and states of the channels. Fewer than the requested number of bytes will be transferred if the source channel has fewer than count bytes remaining, or if the source channel is non-blocking and has fewer than count bytes immediately available in its input buffer.
Hence, using `Long.MAX_VALUE` seemed to be the standard way to transfer all bytes from one channel to the other.
However, it appeared that for some reason on a subset of old Android devices, the device tries to allocate `count` bytes of memory before transferring the bytes. Obviously, this caused a crash because no device has that much memory. This was fixed transferring bytes using a 1MB buffer.

This adds https://github.com/mysticatea/abort-controller to polyfill [AbortController](https://developer.mozilla.org/en-US/docs/Web/API/AbortController). This is used to cancel requests when using `fetch`.
This also updates `event-target-shim` to 5.0 to make sure we only have one version of this dependency. This updates required adding a polyfill for `console.assert` which is used by the new version. I made one based on https://github.com/gskinner/console-polyfill/blob/master/console.js#L74.
The polyfill is very small, especially since we already use `event-target-shim` so I think it makes sense to include in core.
Depends on #24418 so that the fetch polyfill supports the `signal` parameter.

Summary:
`[RCTBridge setUp]` and `[RCTBridge invalidate]` execute asynchronously and concurrently. Therefore, it's not safe to call one method after the other, as we do in `[RCTBridge reload]`.
In this test, we create a bridge, and immediately reload it. Initializing the bridge causes the JS bundle to execute. Invalidating the bridge causes the jsThread to be terminated. If circumstances are correct, we could end up trying to executing the JS bundle after the jsThread has been terminated, which can lead to these assertions being triggered:
1. `RCTAssert(_jsThread, @"This method must not be called before the JS thread is created");` in `ensureOnJavaScriptThread:`.
2. `RCTAssert(_jsMessageThread != nullptr, @"Cannot invoke completion without jsMessageThread");` in `enqueueApplicationScript:url:onComplete:`.
```
- (void)testUnderlyingBridgeIsDeallocated
{
RCTBridge *bridge;
__weak id batchedBridge;
autoreleasepool {
bridge = [[RCTBridge alloc] initWithBundleURL:_bundleURL moduleProvider:nil launchOptions:nil];
batchedBridge = bridge.batchedBridge;
XCTAssertTrue([batchedBridge isValid], @"RCTBridge impl should be valid");
[bridge reload];
}
RCT_RUN_RUNLOOP_WHILE(batchedBridge != nil)
XCTAssertNotNil(bridge, @"RCTBridge should not have been deallocated");
XCTAssertNil(batchedBridge, @"RCTBridge impl should have been deallocated");
// Wait to complete the test until the new bridge impl is also deallocated
autoreleasepool {
batchedBridge = bridge.batchedBridge;
[bridge invalidate];
bridge = nil;
}
RCT_RUN_RUNLOOP_WHILE(batchedBridge != nil);
XCTAssertNil(batchedBridge);
}
```
To verify that this race is real, patch: P62410422. This adds an artificial delay in the `[RCTCxxBridge start]` method, which makes it so that the bridge is invalidated and the js thread is destroyed before we start executing the jsBundle.
I think a proper solution to this problem would require some bit of restructuring of `[RCTCxxBridge invalidate]` and `[RCTCxxBridge start]` to either:
1. Force `[RCTCxxBridge invalidate]` to wait for `[RCTCxxBridge start]` to complete and vice versa.
2. Make it safe to interleave execution of `[RCTCxxBridge start]` and `[RCTCxxBridge invalidate]`.
I tried the first approach using two semaphores: `_startSem(1)` and `_invalidateSem(0)`. When you start executing the code inside `[RCTCxxBridge start]`, you `semWait(_startSem)`. When you stop executing the code inside `[RCTCxxBridge start]` (which could happen in another thread at some later point in time), you `semSignal(_invalidateSem)`. Likewise, when you start executing `[RCTCxxBridge invalidate]`, you `semWait(_invalidateSem)` and when you stop executing the code inside `[RCTCxxBridge invalidate]` you `semSignal(_startSem)`. This way, invalidates always wait for starts to finish, and starts always wait for invalidates to finish. But considering all the concurrency involved in these methods, this is hard to get right.
The second approach seems possible. You could keep locks for the shared data, and create critical sections whever you want to access that data. I didn't actually try to implement this approach though.
Given that we're going to elminate the Bridge anyway, and that this race condition practically only occurs when you reload imediately after initializing the bridge (which can only really be done programmatically), I think it's fine to just disable the test for now. One other thing I considered was making the current thread sleep for some time after we created the bridge in the test. The reason why I'm hesitant to implement this approach is that it would slow down the execution of the test suite and still wouldn't guarantee that we don't hit this race condition. Ultimately, our infra might end up disabling these tests again.

This diff replaces all MountItem classes with a bunch of static C functions that do the same job as classes did.
Seems, originally we overestimated the complexity of MountItem classes and that they ended up being notably trivial. Now, maintaining that even longer would mean paying for abstractions and allocations that we don't really need and writing a lot of tedious code.
Besides that, the one particular change that will be introduced in the coming diffs is not particularly fit very well in the existing class-based model.
This change also should save us many hundreds of allocations and atomic counters bumps, so maybe we can get a millisecond-or-two win.
This diff does not introduce any practical behavioral/logical changes in the mounting layer.

Summary:
Motivation is following - I'm sure many people encountered this because it has been like this for a long time.
1 . you're developing something on android, HMR and dev mode is enabled
2 . you go to dev settings, you disable dev mode because you want to see how something behaves
3 . you reload the app because that's what is required for the change to take effect
4 . you wait for the bundle to be compiled and served, and when that is done, you get an error message about HMR not being a registered callable module - because HMR is not available when `__DEV__ === false` (todo screenshot)
this fixes the described case by checking if HMR is enabled and dev mode disabled when reloading (step 3) and disables HMR in that case.
this also fixes the case when dev mode is disabled and without knowing it, you try to enable HRM (will enable both dev hmr and dev mode).

There is a problem rendering text shadows on iOS. If the offset of the text shadow is `{width:0,height:0}`, the shadow does not display. This prevents you from representing a light directly above the text. This occurs because a text shadow only renders if the offset is a non-zero CGRect `{width:0,height:0}`.
My change checks `textShadowRadius` instead. If `textShadowRadius` is not nan then the user is rendering a text shadow. There are no situations to render a shadow without `textShadowRadius` making it a good variable to check.

For props that expects a struct/object value, like scrollView's contentInset, not all keys may be present. For example:
```
<ScrollView ... contentInset={{top: 10}} />
```
In this example, `left`, `bottom`, and `right` should just default to 0 (or whatever the default is in the platform). Before this fix, an exception occured when calling `fromRawValue()` because it is assuming all 4 keys are present in the prop bag. However, only `top` key was present in this example.
To fix this, we have to loop through the available keys in the prop bag, then assign the values accordingly.

Summary:
In the case where the first rootView we load enables Fabric, the UIManagerBinding ended up calling AppRegistry (JS) too early, before the bridge was fully ready. This means AppRegistry wasn't set up yet, causing redbox.
To fix this, RuntimeExecutor impl should ask the bridge to queue the callback instead of asking the MessageQueueThread directly. MessageQueueThread only works well IFF the bridge is alive, but it has no knowledge about whether the bridge is alive or not. To support this, we add `invokeAsync` impl to the RCTCxxBridge.
