add local focus mode and input event injection API to Window
- This enables keyboard navigation for window without focus.
- FLAG_LOCAL_FOCUS_MODE puts window into local focus mode.
- Application needs to put window in local focus mode, control focus, and
inject events to make dpad navigation work.
- Window in local focus mode does not interact with window manager or ime
regarding focus related events.
- Also renamed ViewRootImpl.dispatchKey to dispatchInputEvent to allow both key and touch events injection.
