tests: Convert test-npot-texture to Cogl

Browse Source 
This updates the npot-texture test to use Cogl directly instead of
relying on Clutter.

Note that this currently fails when Cogl ends up using sliced
textures. It looks like there is some bug with the meta texture
function to iterate the primitive textures. This happens when
COGL_DEBUG=disable-npot-textures is set.
