mesa: remove fallback for GL_DEPTH_STENCIL

Browse source 
st_TexSubImage has this "default to fallback for depth-stencil" since
2013. I think it's time to remove this limitation - hopefully all
drivers will be happy with the change to avoid adding yet another CAP.

This helps CS:GO startup a lot, because the fallback path is very very
slow.
