drm/amd/display: Test cursor commit

Browse source

[WHAT]
Add KUnit tests for amdgpu_dm_commit_cursors() covering an empty commit,
a non-cursor plane, and a cursor update, and for amdgpu_dm_update_cursor()
covering missing framebuffers and removal of an active stream cursor.

[HOW]
Reuse the single-plane commit fixture. The disable path uses the real
state-only DC cursor position setter without hardware programming.
