Summary:
Per discussion in the previous diff D33672110, it's ok to add the `pointerEvents` prop to scrollview. This will help prevent scrolling on the ScrollView if pointerEvents is set to `box-none`, or `none`.
Corresponding doc changes are in https://github.com/facebook/react-native-website/pull/2936
Changelog:
[Android][Added] - Add new API in ScrollView and HorizontalScrollView to process pointerEvents prop.

In the case of T110060790, there is a JavaScript crash that causes RN teardown to race with a ScrollView event being emitted, which ends up being reported as the "real" cause of the crash.
This is not correct, and it's better to just ignore this case. If there's no EventDispatcher, it means something has gone wrong (usually teardown) before, RN is in an inconsistent state, and we should
not crash here or report here.

Summary:
MapBuffer uses unsigned short in C++, but Java doesn't really have a type that represents that. That means that MapBuffer would be limited to max 32768 values instead of 65536, which doesn't make much sense as a limitation.
Considering weird (and usually not performant) handling of short values in Java in general, this change replaces them with ints, converting keys from short when needed with `key & 0xFFFF`.

Summary:
This diff adds `overflowInset` values in RN Android. These values are used to give an enlarged boundary of a view group that also contains all its children layout. Here is [the post](https://fb.workplace.com/groups/yogalayout/permalink/2264980363573947/) that discuss more on why this is useful. I steal the pic in that post here as TLDR:
{F687030994}
In the above case, we will get overflowInset for ViewGroup A as something like `top: 0, right: -20, bottom: -20, left: 0`.
This has been added in the [Fabric core](https://fburl.com/code/f8c5tg7b) and [in IOS](https://fburl.com/code/vkh0hpt6). In Android, since we used to ignore all event coordinates outside of a ViewGroup boundary, this is not an issue. However, that caused unregistered touch area problem and got fixed in D30104853 (https://github.com/facebook/react-native/commit/e35a963bfb93bbbdd92f4dd74d14e2ad6df5e14a), which dropped the boundary check and made the hit test algorithm in [TouchTargetHelper.java](https://fburl.com/code/dj8jiz22) worse as we now need to explore all the child node under ReactRootNode.
This perf issue is getting obvious when a view loads too many items, which matches our experience with "Hover getting slow after scrolling", "Hover getting slow after going back from PDP view", and "The saved list view (in Explore) is very fast (because it has very few components)"
To fix this issue, I added the support to `overflowInset` to RN Android by
1. Sending the `overflowInset` values from Binding.cpp in RN Android as a separate mount instruction
2. Update `IntBufferBatchMountItem.java` to read the int buffer sent over JNI, and pass the `overflowInset` values to `SurfaceMountingManager.java`
3. Creating new interface `ReactOverflowViewWithInset.java` and extending the existing `ReactOverflowView.java` usages
4. Adding implementation of getter and setter for `overflowInset` in various views
5. Update `TouchTargetHelper.java` to read the values and check boundaries before exploring ViewGroup's children
Note that in #3 I didn't change `ReactOverflowView.java` interface directly. I am concerned about backward compatibility issues in case this interface is being used in OSS. I suggest we deprecate it as we are not using it anymore in our code.

Summary:
This diff add custom prediction for fling distance support. This is needed for customize fling animator to calculate predicted fling distance, instead of using the overscroller that may not be used by the animator.
More context on this -- when fling happens, our code will first predict the final fling position `p`, apply the snapping logic to decide the expected snapping position `pSnapping` given `p`, scroll velocity and children layout, then trigger the overscroller (existing) or custom fling animator to finish the fling.
Currently, the prediction logic is done with overscroller, and custom fling animator has no control over how the predicted fling distance should be. Changes in this diff allow the animator to override `getExtrapolatedDistance` method and provide that information.

Summary:
This diff fixes two edge case (similar to a race condition) that caused unexpected behaviors.
**Problem one**
{F680816408}
The previous fling animation is not canceled when user starts to scroll or drag. This is causing both the animation and scroll are setting the scroll position. Depends on the animation path and scroll speed, there may be cases where the [velocity calculation](https://fburl.com/code/010lsu72) ends up getting reversed values. See P467905091 as an example where you can see `mXFlingVelocity` goes back and forth from positive to negative.
It's hard to see if the wrong values are in the middle, but if that happens in the end of user gesture, the velocity for the next fling would be wrong. It shows a "bounce back" effect, and can be triggered when user makes small quick joystick scrolls in one direction.
**Problem two**
{F680821494}
There is a gap between animator's `onAnimationEnd` lifecycle method [finished](https://fburl.com/code/6baq04ne) and the `Animator#isRunning` API to return false. This is causing issues for `getPostAnimationScrollX` where we [decide to return](https://fburl.com/code/hzzugvch) the animated final value or the scroll value. User may see the `-1` value got used for the next fling start value, and the whole scroll view goes back to the beginning of scroll view and starts to fling.
This happens when the previous fling animation finishes and the animated final value is set to -1, but at the same time the next fling starts before `isRunning` returns false for the previous animation.
**Solution**
The problems are fixed by
- Do not reset animated final value to -1 in `onAnimationEnd` method
- Add `mIsFinished` states and use it to track animation finish signal, instead of using `isRunning` API
- Update logic where we decide to return the correct value for the next animation starts point. We will return previous animated final value when the animation got canceled, and user is going towards that value from the current scroll value.

Summary:
This diff makes the fling animator cuztomizable, so that the subclasses can have their own animation for fling behavior.
Before the diff, we rely on the `OverScroller` to `fling`, which has some issues with Spline interpolation being messed up due to the clamped fling distance (See more details in T105464095). This may not be a big issue for mobile when user touches screen, but in VR environment this shows up very clearly with joystick events. To fix that properly without affecting mobile behavior, I added a new interface `HasFlingAnimator` from the helper, and implemented with default fling animator in the OSS ScrollView.
We should consider adopt a suitable animator for mobile platform, as the non-smooth fling effect is also happening in mobile.
- Add interface `HasFlingAnimator` to `ReactScrollView` and `ReactHorizontalScrollView`
- Add default fling animator
- Depend on if the default animator is used, customize the flingAndSnap behavior

Summary:
This bug is caused by RNAndroid dispatching an incorrect sequence of events to JS when the user taps on a Text.
Taking into consideration the example P462662009, when the user taps of the "Inner" text, RN Android is dispatching three events:
topTouchStart, topTouchStart and topTouchEnd.
The information stored on the first two JS events is correct, but the problem is that it is duplicated. This sequence of events makes Pressability to dispatch the event to the incorrect target.
This was originally introduced in D3035589 (https://github.com/facebook/react-native/commit/39fdce259dd46de8fd715efbfd12ede4bc24c8c2) (2016)
In this diff I'm changing the way RN Android bubbles events when the user taps on a ReactTextView. From now on, events won't be bubbled anymore, and they will be handled by the ReactRootView.onInterceptTouchEvent: https://fburl.com/code/rbt8$
Additionally, I'm creating a FeatureFlag in case this change has a unknown side effect that's only detected in production.
I will create a MC for FB4A in the next diffs of the stack

These two props were implemented in C++ and iOS but never supported in JS.
Pre-Fabric (and CSS) on the other hand use a single prop `textDecorationStyle: 'solid' | 'double' | 'dotted' | 'dashed'`.
