tests/perf_pmu: Avoid RT thread for accuracy test
Realtime scheduling interferes with execlists submission (tasklet) so try
to simplify the PWM loop in a few ways:
* Drop RT.
* Longer batches for smaller systematic error.
* More truthful test duration calculation.
* Less clock queries.
* No self-adjust - instead just report the achieved cycle and let the
parent check against it.
* Report absolute cycle error.</pre>
