Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/38648https://github.com/facebook/react-native/pull/38475 made this code no longer no-op on Android, which caused regressions documented in https://github.com/facebook/react-native/issues/38470#issuecomment-1639620459 due to VirtualizedList having more out-of-date information.
We are already coalescing scroll events on both Android and iOS, which will ensure we are not flooded with events. VirtualizedList also already inserts an artificial 50ms delay to new renders by default when high priority work is not happening (see `updateCellsBatchingPeriod`). This limits the heavy work done by VirtualizedList (no new renders or expensive math on scroll events), while letting the list still have the most recent events.
We can eventually remove this once VirtualizedList is able to use OffScreen universally.

[General][Changed] - Remove default 50ms Scroll Event Throttling in VirtualizedList

This extracts the state and logic VirtualizedList uses to query information related to cell metrics. We will need to modify this (and other places) when fixing up RTL support for horizontal FlatList.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37778
These functions describe how to get the metrics of a specific cell. "Frame" here seems non-descriptive and redundant to the "Metrics" part. Renaming this before a larger refactor.

Summary:
CellRendererComponent can be given a more useful description, and more constrained type, to ensure it is used more correctly.

Summary:
This change reverts D41745930 (https://github.com/facebook/react-native/commit/2e3dbe9c2fbff52448e2d5a7c1e4c96b1016cf25) as part of a stack to splice back source history which was lost (Git registered the file moves as additions).
It is expected this diff will individually fail. The entire stack should be applied at once.
