Summary:
Nothing behavioral changed in this diff; just moving code around.
`RCTBackedTextInputDelegate` is the new protocol which supposed to be common determinator among of UITextFieldDelegate and UITextViewDelegate
(and bunch of events and notifications around UITextInput and UITextView).
We need this reach two goals in the future:
* Incapsulate UIKit imperfections related hack in dedicated protocol adapter. So, doing this we can fix more UIKit related bugs without touching real RN text handling logic. (Yes, we still have a bunch of bugs, which we cannot fix because it is undoable with the current architecture. This diff does NOT fix anything though.)
* We can unify logic in RCTTextField and RCTTextView (even more!), moving it to a superclass. If we do so, we can fix another bunch of bugs related to RN imperfections. And have singleline/multiline inputs implementations even more consistent.
