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.
