actor: separate the queue redraw code

Browse Source 
clutter_actor_queue_relayout currently queues a relayout and a redraw,
but the plan is to change it to only queue a relayout and honour the
documentation by assuming that the process of relayouting will
result queuing redraws for any actors whos allocation changes.

This doesn't make that change it just adds an internal
_clutter_actor_queue_only_relayout function which
clutter_actor_queue_relayout now uses as well as calling
clutter_actor_queue_redraw.
