Add support for ETC2 compressed textures in the etnaviv driver.
One step closer towards GL ES 3 support.
For now, treat SRGB and RGB formats the same. It looks like these are distinguished using a different bit in sampler state, and not part of the format, but I have not yet been able to confirm this for sure.
(Only enabled on GC3000+ for now, as the GC2000 ETC2 decoder implementation is buggy and we don't work around that)
