drm/amd/display: Test PSR dirty rectangle filling

Browse source

[WHAT]
Add KUnit tests for fill_dc_dirty_rects() covering the cursor plane
bypass, the full frame update fallbacks taken on rotation, on a
damage-unaware client, on ignored damage clips, on exceeding
DC_MAX_DIRTY_RECTS and on PSR SU in auto damage mode, the verbatim copy of
damage clips, and the MPO paths for a moved plane, a flipped plane, stable
clips and clips that overflow together with the bounding boxes.
