drm/amd/display: Test optional plane property creation

Browse source

[WHAT]
Add KUnit tests for amdgpu_dm_plane_init() covering the rotation
property and framebuffer damage clips on newer ASICs, and the default
color pipeline on DCN 3.0 and newer.

[HOW]
Initialize an overlay plane on a standard DRM KUnit device, varying
the ASIC type, the DCE IP version and the DC context DCE version to
select each optional property.
