[mutter/wip/nielsdg/use-g-declare-interface: 52/53] clutter: MasterClock: Use G_DECLARE_INTERFACE()

[Jonas Ådahl <jadahl src gnome org>]

commit 41a69f194d6333d654b5a82a364fae73d27452b5

    clutter: MasterClock: Use G_DECLARE_INTERFACE()
    
    It cuts away a bit of the GObject boilerplate, gives us support for
    `g_autoptr`, and removes the typedef hack inside clutter-master-clock.c.
