[mutter] clutter/actor: Remove "allocation-changed" signal

[verdre <jonasd src gnome org>]

commit e50e14af8283582882b198f79ca8ed01de220e94
Author: Jonas Dreßler <verdre v0yd nl>

    clutter/actor: Remove "allocation-changed" signal
    
    Since we now no have ClutterAllocationFlags, there's no reason anymore
    for keeping the "allocation-changed" signal, so remove it.
