Fix a typo at line 353 of text_input_channel.cc (the else statement should come after #endif).
Let TextInputChannel::SendKey return false by default and check if the given key is actually handled by HandleKey. This fixes a problem of back button not responding when a TextField has a focus and a software keyboard is closed.
Change the return type of PlatformViewChannel::SendKey to bool to allow platform views to intercept key events without propagating to other handlers.
Note: TextInputChannel::HandleKey handles only key down events and thus some key up events (Left, Home, and etc.) are still redundantly propagated to PlatformViewChannel and KeyEventChannel.
