clutter/actor-meta: Add a new 'set_enabled' vfunc

Browse Source 
Various subclasses of ClutterActorMeta need to reacto to being
disabled. Right now, however, the only way to do that is by
overriding GObject's 'notify' vfunc, and doing a string comparison
against "enabled".

Add a new vfunc to ClutterActorMeta in order to replace this bad
practice.
