svga: enable MSAA for SM4_1 device

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

The SVGA device is deprecating the DX9 MSAA support. This patch enables MSAA for SM4_1 device by explicitly setting the SVGA3D_SURFACE_MULTISAMPLE bit. For SM4_1 device, only 4 samples is supported.
