drm/amd/display: Fold blending tests into two cases

Browse source

[WHAT]
Reduce the five KUnit tests for
amdgpu_dm_plane_fill_blending_from_plane_state() to two, keeping every
covered path.

[HOW]
Turn the opaque, premultiplied and coverage cases into one table-driven
test over the pixel blend mode, and fold the DCN 4.2 case into the
global alpha test as a second table row selecting the DCE IP version.
