drm/amd/display: add KUnit tests for audio commit path

[WHAT]
Add KUnit coverage for amdgpu_dm_commit_audio(), the remaining function
reported as untested by gcov.

The tests build hand-rolled drm_atomic_state arrays and back
dc_stream_get_status() with a fake dc->current_state to cover the
removal and addition ELD notifications along with their guard/skip
paths: writeback connector, detached connector, missing new CRTC state,
no modeset, and absent stream status.
