drm/amd/display: Test dm_dp_mst_connector_destroy

Browse source

[WHAT]
Add KUnit tests for dm_dp_mst_connector_destroy() covering the teardown
of a connector that never had a remote sink, and the teardown that first
removes the remote sink from the DC link.

[HOW]
The function frees both the connector and the MST port, so the test
allocates them outside the KUnit managed allocator. The parent branch
device takes an extra malloc reference so it survives the port teardown.
