[mutter/gbsneto/cleanup-x11-from-window-actor: 3/8] Add MetaWindowActorX11 and MetaWindowActorWayland

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 39076eef6c8056b605e821b52ade9ca5e73531db
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>
Date:   Fri Dec 21 18:35:18 2018 -0200

    Add MetaWindowActorX11 and MetaWindowActorWayland
    
    Those are stub specialized classes for MetaWindowActor. This will
    help ensuring that we do not execute X11-specific code paths on
    pure Wayland clients.
    
    The relationship between the window actor and the surface is the
    following:
    
     * Wayland: MetaWindowActorWayland + MetaSurfaceActorWayland
     * X11: MetaWindowActorX11 + MetaSurfaceActorX11
     * Xwayland: MetaWindowActorX11 + MetaSurfaceActorWayland
    
    It is not possible to have MetaWindowActorWayland backed by a
    MetaSurfaceActorX11 surface.
