drm/amd/display: Test plane update adapter

Browse source

[Why]
Add KUnit tests for update_planes_and_stream_adapter() covering
descending plane sorting, argument forwarding, call ordering, and
DC failure propagation.

[How]
Extend the existing DM KUnit ops table with the two DC calls and use
spies to observe inputs and ordering. Reuse one ops installer for the
adapter and MMHUB tests.
