Changelog: [General] [Changed] - fix item disappearing with scroll in VirtualizedList
It was caused because the function `computeWindowedRenderLimits` collapsed the current window size to just 1 element. So, users start scroll current window increase from {left:0, right:5 } -> {left:0, right:6 } and after some edge cases the window collapsed to `{left:6, right:6 }` which cause to remove all elements and recreate them later. As a result users have a lot of lags and blank pages.
The diff fixes the collapsing window size to 1 element. Also fix other decreasing `left` position even if windowSize more than current amount of elements.

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.

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:
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.
