drm/amd/display: move scaling helper to connector

Browse source

[WHAT]
amdgpu_dm_update_stream_scaling_settings() computes the stream src/dst
rectangles for a connector's scaling mode. It is already declared in
amdgpu_dm_connector.h and consumed by create_stream_for_sink(), so move
its definition out of the oversized amdgpu_dm.c into
amdgpu_dm_connector.c where it belongs.

Relocate its KUnit tests from the amdgpu_dm suite to the
amdgpu_dm_connector suite accordingly. No functional change.
