shaped-texture: Move MetaCullable helpers to MetaSurfaceActor

Browse Source 
Now that MetaShapedTexture is not a ClutterActor anymore, it does
not make sense to make it a MetaCullable semi-implementation. This
is, naturally, a responsibility of MetaSurfaceActor, since now
MetaShapedTexture is a ClutterContent and as such, it only cares
about what to draw.

Move the MetaCullable implementation of MetaShapedTexture to
MetaSurfaceActor.
