RCTTextField was spliited into two classes

Summary:
Motivation:
 * We maintain two different implementation of <TextInput> (multilined and singlelined), this change makes the implementations much similar which will help us to support and improve both of them in the (near) future;
 * We have to have separated RCTView-based container view for (TextField) to support sofisticated bordering and so on;
 * It opens to us possibility to unify UITextView and UITextField subclasses and remove code duplication across RCTTextView and RCTTextField;
 * Making things decoupled in general will allow us to fix existing bugs with events.
