Fix touch events not being dispatched to ScrollView's children when they overflow content container (facebook#49855)

Summary:
Pull Request resolved: facebook#49855

Changelog: [IOS][FIXED] - Fixed touch events not being dispatched to ScrollView's children when they overflow the content container

Closes facebook#47740.

Changes the ScrollView's container view to be `RCTViewComponentView` instead of `UIView` and sets custom layout metrics to it in a way that it will propagate touch events to all children, even if they overflow its bounds.
