intel/common/xe2+: Allow SIMD32 PS for all multisample cases.

Browse source 
These don't seem to be disallowed by recent hardware anymore.  Stop
disabling SIMD32 due to hardware restrictions of multisample
rasterization, since it should have better performance, and on Xe3+
there may be no shader variant available other than SIMD32.
