svga: add support for FS sample mask output

Graphics / Mesa 3D Graphics Library / Mesa - Brian Paul [vmware.com] - 10 September 2018 19:07 EDT

This, with the previous work for sample position/id query, allows us to enable per-sample shading for VGPU 10.1.

Note that quite a few Piglit arb_sample_shading tests still do not pass, but many do.
