Summary:

ReactTextInputManager only sets up the watchers behind onKeyPress, onSelectionChange, onContentSizeChange and onScroll once it receives the matching prop. AndroidTextInputProps had no fields for these props, so getDiffProps never sent them and the events never fired with props diffing on. TextInput.js always passes onScroll and onSelectionChange, so every TextInput would be affected.

The problem above appears when the enablePropsUpdateReconciliationAndroid flag is enabled.

Changelog:

[Internal] - Send TextInput event props when props diffing is enabled

Test Plan:

AndroidTextInputPropsDiffTest.eventHandlerPropsAreSent compares the props diffing payload with the raw props payload. It fails without this change and passes with it. python -m scripts.cxx-api.parser --validate passes at this commit.

Summary:
`ReactTextInputManager` only sets up the watchers behind `onKeyPress`, `onSelectionChange`, `onContentSizeChange` and `onScroll` once it receives the matching prop. `AndroidTextInputProps` had no fields for these props, so `getDiffProps` never sent them and the events never fired with props diffing on. `TextInput.js` always passes `onScroll` and `onSelectionChange`, so every TextInput would be affected.

This adds the fields and sends them. JS sends a handler as `true`. Removing a handler sends `false`, which the setters treat the same as the `null` sent by raw props.

TextInput doesn't use props diffing yet: `getDiffPropsImplementationTarget()` returns `TextInput`, which doesn't match the `AndroidTextInput` component name. So the problem above only appears once that is enabled, and this change has no runtime effect until then.
