mesa: add GL_OES_gpu_shader5 and GL_EXT_gpu_shader5 support
The two extensions are identical, and are largely taking bits of already
existing desktop functionality. We continue to do a poor job of
supporting the 'precise' keyword, just like we do on desktop.
This passes the relevant dEQP tests that I could find.
