[Mesa-dev] [PATCH] virgl: Expose GL_ARB_copy_image if host supports it

Note that I used (1 << 3) instead of (1 << 2) because Dave's experimental patch
already uses the latter for computer shader caps. 
The host side patch starting to implement this can be found here: 
  https://patchwork.freedesktop.org/series/45064/

Thanks for reviewing, 
Gert
