Turn ClutterBindingPool a GObject

Browse Source 
ClutterBindingPool is already "problematic" in terms of memory
management for language bindings and gobject-introspection. It
also lacks a GType.

Turning ClutterBindingPool into a GBoxed would not make much
sense, since it does not adhere to the copy/free semantics. It
could be referenced/unreferenced, but in that case we can just
as well use GObject as a base class instead of reimplemeting
a ref-counted object and then boxing it.

ClutterBindingPool is obviously a terminal class, so we just
hide the instance and class structures.
