drm/amd/display: Add KUnit tests for amdgpu_dm_replay

Browse source

[WHAT]
Add KUnit coverage for amdgpu_dm_set_replay_caps(),
amdgpu_dm_link_setup_replay(), and amdgpu_dm_replay_set_event()
including happy-path tests that exercise the configuration logic,
coasting vtotal calculations, and early-return when replay events
are already in the desired state.
