drm/amd/display: Test CRTC color management update

Browse source

[WHAT]
Add KUnit coverage for amdgpu_dm_check_crtc_color_mgmt() and
amdgpu_dm_update_crtc_color_mgmt().

A shared color-update fixture (adev/DC, atomic state, CRTC/stream and
plane state) backs the tests: the check path succeeds with no CRTC LUTs,
and the update path leaves the stream gamut remap bypassed without a CTM
and enables it when a CRTC CTM is present.
