window-actor: Turn into a derivable class

We will introduce specialized MetaWindowActors for X11
and Wayland in the future, so it needs to be derivable.

Make it a derivable class, and introduce a private field.
The MetaWindowActorClass definition is in the private
header in order to prevent external consumers of Mutter
to create MetaWindowActor implementations of their own.
That is, MetaWindowActor is only internally derivable.
