drm/amd/display: set stream gamut remap matrix to MPC for DCN3+

dc->caps.color.mpc.gamut_remap says there is a post-blending color block
for gamut remap matrix for DCN3 HW family and newer versions. However,
those drivers still follow DCN10 programming that remap stream
gamut_remap_matrix to DPP (pre-blending).

To enable pre-blending and post-blending gamut_remap matrix supports at
the same time, set stream gamut_remap to MPC and plane gamut_remap to
DPP for DCN families that support both.

It was tested using IGT KMS color tests for DRM CRTC CTM property and it
preserves test results.
