Refactor key event handling (#291)

* Removes platform dependencies from all SendKeyEvent methods.
* Adds methods related to composing a text to the FlutterView and
  TextInputChannel.
* Transfers the key event filter role to TizenInputMethodContext.
* Adds filter methods for each event type to TizenInputMethodContext.
* Removes the concept of selection mode for text input.
