drm/amd/display: Test plane colorop pipeline update

Browse source

[WHAT]
Add KUnit coverage for the colorop-pipeline path of
amdgpu_dm_update_plane_color_mgmt().

Test-local helpers fabricate a linked colorop pipeline so the update path
can be exercised end to end: a fully bypassed pipeline succeeds, a
pipeline missing the multiplier or the 3x4 op falls back to defaults, and
a pipeline with no 3D LUT hardware skips the 3D ops.
