drm/amd/display: Fold plane state check tests

Browse source

[WHAT]
Reduce the four viewport KUnit tests for
amdgpu_dm_plane_helper_check_state() to one, and the three rejection
tests for amdgpu_dm_plane_atomic_check() to one.

[HOW]
Drive the viewport cases from a table of CRTC rectangles and display
sizes, and rebuild the atomic state between the helper-check, color
pipeline conflict and scaling-info sub-cases of the atomic check test.
