Add support for ETC2 compressed textures in the etnaviv driver.
These are available on GC2000+.
One step closer towards GL ES 3 support.

Mesa does not export the ETC2 formats without OpenGL ES 3, so to test, use:
export MESA_GLES_VERSION_OVERRIDE=3.0
Currently no distinction is being made between RGB and SRGB formats. I'm still
researching the state bits concerned with that.
