drm/amd/display: Cover amdgpu_dm_update_connector_after_detect

Browse source

Add KUnit tests covering amdgpu_dm_update_connector_after_detect(): the
MST-sink early return, connect with and without EDID, disconnect teardown,
and the four forced emulated-sink paths. Sinks the function releases to
zero use real allocations while retained sinks use kunit-managed memory to
keep dc_sink refcounting balanced.
