drm/amd/display: Add KUnit tests for watchdog and cpirq events

Browse source

Verify event_watchdog_timer() cancels its pending watchdog_dwork
and runs process_output(), and that event_cpirq() runs
process_output() without arming the callback or watchdog timers.
Both release the work-queue mutex on return.
