Add rejectResponderTermination prop to TextInput (#16755)

Summary:
This is a new attempt to get #11251 merged. I just cherry-picked the relevant commits. TextInputs are set to always ignore responder termination requests, which is not desirable when they are enclosed inside a swipeable area like a ListView

Create a TextInput inside a ListView and set the `rejectResponderTermination` prop to false. Otherwise, all TextInputs should have the same behavior they do now.

[IOS] [ENHANCEMENT] [TextInput] - Add `rejectResponderTermination` prop to to TextInput. This enables TextInputs inside Swipeables to function properly.
