clutter: Remove ability to externally set sync-to-vblank

Browse Source 
Externally setting the sync-to-vblank setting was a feature
added as a workaround to old Intel and ATI graphic cards, and
is not needed anymore. Furthermore, it doesn't make sense to
change it on a compositor whatsoever.

This commit removes all the ways to externally change this
setting, as well as the now unused API.
