Rafal Ostrowski 4195148325 drm/amd/display: Migrate color manager HW and fix MCM blend LUT issues 
Combine two related color manager improvements:

1. Migrate MCM/RMCM, shaper and 3DLUT HW programming to dc_plane_cm
   - Continue convergence with upstream Color Manager refactor
   - Migrate MCM/RMCM, shaper and 3DLUT programming for dcn401+ to dc_plane_cm
   - Unify MCM programming across both legacy and 3DLUT DMA paths
   - Add 3DLUT DMA broadcast support for multi-pipe planes

2. Reprogram MCM blend LUT on blend_enable falling edge
   - Fix issue where SDR desktop remained desaturated after video playback
   - Detect blend_enable falling edge (1->0) in surface update detection
   - Force MCM LUT reprogramming on blend state change
