Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/54115

Horizontal scroll view extensions should be able to  customize the scrolling behavior for state restores. This adds the `restoreScrollTo` function that will be called to restore the scroll position to the location provided by the shadow node state.
