Fabric: ScrollViewComponentView: Calling `onScrollEndDrag` in `scrollViewDidEndDragging:`

Summary:
* Previously we called `onScrollEndDrag` in `scrollViewWillEndDragging` which was not correct.
* Now we also call `_updateStateWithContentOffset` in the method to update the stored in state `contentOffset`. This fixes all `measure*` infra.

Changelog: [Internal] Fabric-specific internal change.
