[clutter] Add internal constructor function for each backend

commit 7ca28e09746f3f1a6b240a8c1a416dd4ad6c8ff6
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Fri Dec 11 14:23:38 2015 +0000

    Add internal constructor function for each backend
    
    We're going to use it to create an instance of each backend without
    using the get_type() function.
