anv: Enable MSAA compression

Browse Source 
This just enables basic MSAA compression (no fast clears) for all
multisampled surfaces.  This improves the framerate of the Sascha
"multisampling" demo by 76% on my Sky Lake laptop.  Running Talos on
medium settings with 8x MSAA, this improves the framerate in the
benchmark by 80%.
