clutter: Prepare input focus for IM event delivery

Browse Source 
The clutter_input_focus_filter_key_event() function has been made
a more generic filter_event(). Besides its old role about letting
key events go through the IM, it will also process the IM events
that are possibly injected as a result.

Users have been updated to these changes.
