[gnome-shell] [St] Remove _st_actor_contains()

[Florian Müllner <fmuellner src gnome org>]

commit 766b5b801c1a23d1e8c346f29664f3a68ffe4816

    [St] Remove _st_actor_contains()
    
    The function has been upstreamed as clutter_actor_contains() - with
    the switch to clutter-1.4 it is now available to the Shell, so it
    is no longer necessary to keep a copy in-tree.
