Feedback Loop Redesign 3/3: Remove feedback loop tracking. We now we detect feedback loops by tracking the Framebuffers that the Texture is bound to. We still have the old tracking method that counts sampler and image bindings in the code as well. This CL removes the old front-end tracking for feedback loops. It's no longer used by any back-ends. This removal should reduce CPU overhead around Texture and Program binding changes. Reverts the image binding tracking to the simpler scheme that tracks if a Texture has ever been bound as an Image. This should practically have little or no perf effect and we can reinstate some simpler tracking in the future if required.
