anv: Enable MSAA compression
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%.
