window-actor: Make freezing and thawing of actor updates public API

Browse Source 
As explained in the last commit, gnome-shell needs to be able to thaw
window actor updates during its size-change effect is active.

So make meta_window_actor_freeze() and meta_window_actor_thaw() public
API, which will allow the shell to freeze and thaw actor updates itself.
