Summary:
This diff changes how we apply default text attributes to backed text input.
The original change in https://github.com/facebook/react-native/pull/23585 that introduced the `reactTextAttributes` field in for RCTBackedTextInputViewProtocol was great! Thank you Wu zhongwuzw !
However, there is one detail that needs to be changed.
RCTBackedTextInputViewProtocol is designed to only abstract complexity of iOS text input components (UITextView and UITextField); it intentionally does not have any React-specific fields or types. Adding a field `RCTTextAttributes *reactTextAttributes;` violates this principle and make it hard to reuse this functionality in the new Fabric-powered TextInput.
This diff changes the type of this prop from `RCTTextAttributes` to `NSDictionary<NSAttributedStringKey,id> *` (exact same type that UITextView and UITextField use).
