Summary:
We introduce a few optimizations:
(1) Previous diff: We defer calling any NativeAnimatedModule methods by waiting 1ms before flushing the queue, and debouncing until no flush is requested. Practically, this just means that we'll call NativeAnimatedModule methods N times at once, at the end of a render loop, instead of N times smeared throughout the render loop.
(2) Additionally, instead of calling N methods, we create multi-operation argument buffer and call a single NativeAnimatedModule API, which should essentially throttle NativeAnimatedModule API calls to once-ish per frame. On the native side, this also reduces a lot of overhead associated with scheduling work on the UI thread (we schedule 1 function to run on the UI thread and perform N operations, as opposed to scheduling N functions to run on the UI thread).
TODO:
- implement stubs for iOS
- write gating code so this can be properly tested in VR and in fb4a

Summary:
Because of the disconnect between the ReactJS render loop and Animated nodes, we don't know when a render loop begins or ends. Historically we haven't cared about that much,
but now for perf reasons we're attempting to batch them. Scheduling a function to execute at the end of the runloop and canceling until nothing interrupts it achieves that.
Impact seems fairly minimal and this should work everywhere (android, ios, etc) but we may want to gate the behavior as it *could* change things in surprising ways.

Summary:
elementsThatOverlapOffsets was quite inefficient as it was doing a linear scan over all items without an early out for each input offset.
The number of items can be large, so we'd want to use binary search here.
Before: O(MN), where M is the # offsets and N is the # items
After: O(MlogN)
As a utility method, elementsThatOverlapOffsets should not be responsible for checking that the offsets are in increasing order

Summary:
This patches a loophole in the logic that caused some operations to execute immediately and some to be deferred, even within the same render loop. This caused the non-queued operations to be executed out of order. Instead, if an operation is created and a queued exists, we just push the operation to the end of the queue so ordering is preserved.

Summary:
Sometimes this._scrollMetrics.offset is 0 even after initial scroll is triggered, because the offset is updated only upon _onScroll, which may not have been called in time for the next computation of the render limits. Thus, there is a window of time where computeWindowedRenderLimits calculates undesired render limits as it uses the offset. This results in 2 extra rerenders of the VirtualizedList if an initial scroll offset is applied, as the render limits shifts from the expected bounds (calculated using initialScrollIndex), to the 0 offset bounds (calculated using computeWindowedRenderLimits due to offset = 0), back to the expected bounds (onScroll triggers recalculation of render limits via _updateCellsToRender).
This issue was introduced in https://www.internalfb.com/diff/D35503114 (c5c17985da)
We cannot rely on this._hasDoneInitialScroll to indicate that scrolling *actually* finished (specifically, that _onScroll was called). Instead, we want to recalculate the windowed render limits if any of the following hold:
- initialScrollIndex is undefined or is 0
- initialScrollIndex > 0 AND scrolling is complete
- initialScrollIndex > 0 AND the end of the list is visible (this handles the case where the list is shorter than the visible area) <- this is the case that https://www.internalfb.com/diff/D35503114 (c5c17985da) attempted to address

Summary:
During debugging of undesired behavior using VirtualizedList with initialScrollIndex, it was found that zoomScale was sometimes undefined, which resulted in elementsThatOverlapOffsets returning not being able to find the frame at the given offsets.
This does not cause any unexpected behavior when scrolling from the top, as the first item index in VirtualizedList is always calculated to be 0; however, when we set initialScrollIndex, the frame calculations are incorrect, resulting in wasteful re-renders of the VirtualizedList as it renders every frame (row) from the top.

[Internal][Fixed] - Default zoomScale to 1 for computeWindowedRenderLimits and elementsThatOverlapOffsets in order to fix render limit calculation.

Summary:
Changelog:
[General][Fixed] - Improved Flow type inference in Animated `.interpolate()`
Improves the ergonomics of `.interpolate()` by allowing Flow to infer the correct type for `outputRange`. This is achieved by adding a new type parameter `OutputT` to `interpolate()` (and `Animated.Interpolation` and `InterpolationConfigType`), which Flow infers as either `number` or `string` based on usage.
Admittedly, at the call site, this is not that much safer compared to something like `outputRange: $ReadOnlyArray<number | string>`, but it does document the intent of the API a bit better and provide some downstream type safety. For example, we can now express `Animated.Number` (D35869375) more precisely by excluding string-valued interpolation nodes.

Summary:
Changelog: [General][Added] - Add `Animated.Numeric` Flow type
Adds a Flow type to represent the various Animated node types that evaluate to numeric values and can be `interpolate()`d.
I'm including `AnimatedInterpolation` as "numeric" here even though it can technically evaluate either to a number or to a string, depending on its config. Note that calling `interpolate()` on a string-valued `AnimatedInterpolation` is a runtime error.
In a future diff, I'm planning to add a type argument to `AnimatedInterpolation` (and its config type), at which point we can refine `Animated.Numeric` to correctly include only `AnimatedInterpolation<number>`.

Summary:
Fixes https://github.com/facebook/react-native/issues/33529 (note that I reproduced the bug on iOS too).
The bug comes from the fact that we were using `this._scrollMetrics.offset` to determine if the initial scroll was done. But sometimes it equals 0 even after the initial scroll is done, for example when the content does not fill the list. So I replaced it with `this._hasDoneInitialScroll`.
I believe that `this._hasDoneInitialScroll` was not used in the first place because it was introduced later (3 years ago vs 5 years ago for the original code).
The replacement correctly fixes the broken test case and the example given in the issue.
Then I had to update two test cases (rename the first and remove the second), that shows explicitly the broken behavior:
we have to simulate the initial scroll for the content to be adjusted, so when the content does not fill the view and the scroll cannot be executed, the content is not adjusted.

Changelog: [Internal][SVC][JS] Refactor the JS base SVC StaticViewConfig to be easier to understand
This diff is a refactor that doesn't change any logic.
# Context
NativeViewConfigs are generated from RCTViewManager in iOS and ViewManager in Android.
StaticViewConfigs are partially generated from JS, and partially handwritten in JS.
We've noticed in at least 2 instances that engineers who add new props to NativeViewConfigs sometimes don't put props in the correct place for StaticViewConfigs, and thus they accidentally break the landblocking jest e2e test that validates the StaticViewConfigs matches the NativeViewConfigs.
The human error is mostly because PlatformBaseViewConfig.js was too nested to be easily understood. This diff refactors PlatformBaseViewConfig.js and adds clarifying comments.
