st/mesa: add support for ARB_texture_multisample (v3)
This adds support to the mesa state tracker for ARB_texture_multisample. hardware doesn't seem to use a different texture instructions, so I don't think we need to create one for TGSI at this time. Thanks to Marek for fixes to sample number picking. v2: idr pointed out a bug in how we picked the max sample counts, use new internal format chooser interface to pick proper answers. v3: use st_choose_format directly, it was okay, fix anding of masks.
