drm/amd/display: Introduce dc_plane_cm and migrate surface update color path

Browse source 
[Why]
Begin convergence with upstream Color Manager refactor
(fda768acb2a1 "drm/amd/display: Sync dcn42 with DC 3.2.373") by
consolidating fragmented per-plane CM state (shaper, 3DLUT, blend,
CM2) into a single dc_plane_cm structure shared by dc_plane_state
and dc_surface_update. Legacy fields are gated behind TRIM_CM2 so
that it keeps compatibility with other repositories.

[How]
Refactored to use newer structures.
No functional behavior change intended. Under !TRIM_CM2 the legacy
fields are still populated for compatibility with other repositories.

v2: squash in conflicting types fix
