Adam Comella c609aee733 iOS: Add onScroll event to TextInput
Summary:
Corresponding Android PR: https://github.com/facebook/react-native/pull/11001

This adds an onScroll event to TextInput which is useful when a multiline TextInput has so much content that it is scrollable.

**Test plan (required)**

Verified the event works properly in a test app. Also, my team uses this event in our app.
