Add onPress prop (facebook#39701)

Summary:
Pull Request resolved: facebook#39701

TextInput already uses Pressability, but doesn't expose the onPress prop. Link:https://github.com/facebook/react-native/blob/main/packages/react-native/Libraries/Components/TextInput/TextInput.js#L1381-L1414.

Currently TextInput only exposes the onPressIn() and onPressOut() props from Pressability. While onPressOut() can serve the same purpose as onPress() in most cases, it doesn't fare well with PanResponder...say a swipe gesture implemented using PanResponder.

When the pointer/cursor exits the hit test bounds of TextInput, onPressOut() will be triggered even though the desired behavior could be that we only want to invoke the event handler when the user lifts their finger from the screen (while still in the hit test bounds of the TextInput).

Example of TextInput in a PanResponder:
