Revert 217768 "Adding key press detection in the browser process."

> Adding key press detection in the browser process.
> It works like this on the browser side: 
> A new object KeyPressMonitor is created on BrowserMainLoop and passed to AudioInputRendererHost to pass to AudioInputController.
> AudioInputController::DoRecord calls KeyPressMonitor::AddKeyPressListener --> KeyPressMonitor listens to system key events through UserInputMonitor(only implemented on Linux) --> AudioInputController::OnKeyPressed is called and sets key_pressed_ --> When AudioInputController::OnData called, it writes key_pressed_ to shared memory along with the audio data buffer.
> On the renderer side a new param "key_pressed" is added through the code path of passing the flag to the webrtc voice engine.
> This CL includes all these changes except the implementation of UserInputMonitor for Windows and Mac. The impl of UserInputMonitor is mostly copied from remoting/host/local_input_monitor_linux.cc
