compositor: Push subsurface order application into apply_state

Browse source 
Seems like it makes sense to have it there, and this cleans up a bunch of
paths where we return status bits so a caller can do this.

We can also drop the explicit setting of view_list_needs_rebuild, as it's
going to happen automatically when applying subsurface order.
