drm/amd/display: Test mod_power stream updates on modeset

Browse source

[WHAT]
Add KUnit tests for amdgpu_dm_mod_power_update_streams() covering empty
and fast commits plus CRTC enable, replacement, and disable, and for
amdgpu_dm_mod_power_setup_streams() covering empty, modeset, and fast
updates.

[HOW]
Leave dm->power_module NULL and PSR/Replay feature bits clear so the DM
stream transition logic runs without a live power module.
