Use the non-deprecated Cogl clipping API

Cogl 1.18 deprecated the global clipping API in favour of the
per-framebuffer one, but since we're using the 2.0 API internally we
don't have access to the deprecated symbols any more.

This is pretty much a mechanical port for all the places where we're
still using the old 1.x API.
