[clutter/wip/wayland: 10/10] Add public CLUTTER_HAS_WAYLAND_COMPOSITOR_SUPPORT define

[Robert Bragg <rbragg src gnome org>]

commit 5659099973dde4c738804b70459fcad11adc75e3
Author: Robert Bragg <robert linux intel com>
Date:   Tue Dec 6 21:53:57 2011 +0000

    Add public CLUTTER_HAS_WAYLAND_COMPOSITOR_SUPPORT define
    
    When clutter has been built with Wayland compositor support then we now
    expose a public CLUTTER_HAS_WAYLAND_COMPOSITOR_SUPPORT define so that
    applications can #ifdef code that depends on the api that this feature
    implies.
