Adds experimental clutter_backend_get_cogl_context API
This adds API to be able to get the CoglContext associated with the
ClutterBackend. The CoglContext is required to use some of the
experimental 2.0 Cogl API.
Note: Since CoglContext is itself experimental API this API should
considered experimental too.
Note: This API is not yet supported on OSX because OSX still uses the
stub Cogl winsys and the Clutter backend doesn't explicitly create a
CoglContext.
