Remove unused MetaCompositor functions

Remove a number of functions that were either entirely unimplemented
or had empty implementations for the Clutter-compositor.

 meta_compositor_begin_move()
 meta_compositor_update_move()
 meta_compositor_end_move()
 meta_compositor_set_active_window()
 meta_compositor_free_window()
