    wayland: Update gtk-shell protocol to v3
    
    This version has 2 new requests:
    - gtk_shell1.notify_launch notifies the compositor that the requesting
      client shall launch another application. The given ID is expected to
      be unique.
    - gtk_surface1.request_focus notifies the compositor that a surface
      requests focus due to it being activated. The given ID is passed to
      this process through undetermined means, if it corresponds with a
      current startup ID and there was no user interaction in between the
      surface will be focused, otherwise it will demand attention.
