Valentin Shergin 5c4979b2a5 Fabric: Using state auto-repeating in RCTSafeAreaViewComponentView
Summary:
This change introducing using `updateStateWithAutorepeat` for state updates in RCTSafeAreaViewComponentView. This way we can reduce the number of active commits and reduce jumps & relayout passes.
The approach with a callback is better than using `_lastPaddingStateWasUpdatedWith` because:
* When we compare the values, we can compare them with actual previous padding numbers stored in Shadow Tree.
* The value stored in a UIView instance can go away because of a view being remounted because of flattening.

Changelog: [Internal] Fabric-specific internal change.
