Summary:

Fixes the issue of not sending TextInput color value to the platform when the props 2.0 are enabled. The change reads color from the textAttributes.foregroundColor because it is parsed into that field in the BaseTextProps, so it doesn't reintroduce #58093.

Changelog:

[Internal] - Fix sending TextInput color prop value when props 2.0 are enabled.

Test Plan:

Added new AndroidTextInputPropsDiffTest.

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.

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:
`AndroidTextInputProps::getDiffProps` never sent `color`. The flat `color` field is not parsed, so the value is only available in `textAttributes.foregroundColor`. Existing text is colored by the attributed string in the state, but the native view kept its default text color, so text typed into an empty input ignored `color`. With a light `color` on a dark background the typed text was black.

This sends `color` from the text attributes, and `null` when it is removed so that `ReactTextInputManager` restores the default text color.

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.
