[mutter] Split out the code that renders the code into a MetaCursorRenderer

[Jasper St. Pierre <jstpierre src gnome org>]

commit d189ddcc86f6aeb0ed25f00209a87d5734c528db
Author: Jasper St. Pierre <jstpierre mecheye net>
Date:   Mon Apr 21 18:05:59 2014 -0400

    Split out the code that renders the code into a MetaCursorRenderer
    
    Right now, this is the same exact same mess it's always been, but
    it will be fixed up soon with backend-specific renderers.
