intel/xe2+: Implement brw_wm_state_simd_width_for_ksp() on Xe2+.

Browse source 
The mechanism for selecting dispatch modes has changed from previous
platforms, add a new implementation brw_wm_state_simd_width_for_ksp()
using the new kernel dispatch controls.

[ Francisco Jerez: Split from a larger patch, handle multipolygon
                   dispatch, add additional comments. ]
