Remove MetaCompositor virtualization

Browse Source 
Now that we only have one compositor, there's no reason to access the
compositor functions through a vtable. Remove the MetaCompositor virtualization
and make the clutter code implement the meta_compositor_* functions
directly.

Move the checks for the compositor being NULL from the vtable wrappers
to the calling code (most of them were already there, so just a few
needed to be added)

Note: the compositor is actually hard-coded on at the moment and the plan
  is to remove the non-composited code entirely, so the checks are
  added only to keep things neat: they have no practical effect.
