tests/clutter/cogl-tex-polygon: Port to CoglPrimitive
Instead of using cogl_polygon(), which uses deprecated API, implement polygon drawing using the CoglPrimitive API family. While the test might have been used to explicitly test cogl_polygon() it could still be useful to test the non-deprecated way of rendering polygons. https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
