drm/amd/display: Add KUnit test for HDCP process_output

Browse source

Expose process_output() as non-static when CONFIG_DRM_AMD_DC_KUNIT_TEST
is enabled and add KUnit tests exercising its full branch logic:

- property_validate_dwork is always enqueued (delay=0)
- callback_dwork is scheduled when callback_needed is set
- callback_dwork is cancelled when callback_stop is set
- watchdog_timer_dwork is scheduled when watchdog_timer_needed is set
- watchdog_timer_dwork is cancelled when watchdog_timer_stop is set
- Both dworks are scheduled independently when both flags are set
