screen-cast/window: Add API to check if stream-cast is active

Browse Source 
Screen-casted windows need to be considered visible in various situations
but existing APIs such as `clutter_actor_is_effectively_on_stage_view()`
don't do so. Add new API that allows checking if a surface belongs to a
screen-casted window for the respective cases.
