drm/amd/display: Fold DCC block mode tests

Browse source

[WHAT]
Reduce the five KUnit tests for the GFX9 DCC block modes of
amdgpu_dm_plane_fill_gfx9_attrs_from_modifiers() to one, and the three
for amdgpu_dm_plane_fill_gfx12_attrs_from_modifiers() to one.

[HOW]
Drive both from a table of modifier bits and the expected HUBP
independent block mode, allocating the device, DC and framebuffer once
and resetting the tiling, DCC and address outputs per row.
