    wayland: Make GdkWaylandWindow public
    
    Allows to access Wayland specific window information like wl_surface and
    wl_shell_surface.
    
    Add gdk_wayland_window_get_wl_surface for getting the Wayland wl_surface
    and gdk_wayland_window_get_wl_shell_surface for getting the Wayland
    wl_shell_surface.
