clutter: Add clutter_event_get_key_state() getter

Browse source 
This function may be used on key events to obtain the fully
detailed pressed/latched/locked modifiers that apply when the
event is received. No events have this detailed information
yet.

This API call may be compared to the clutter_event_get_state_full()
that existed in the past, although this getter has a stronger
predilection to it applying exclusively to key events.
