perf cs-etm: Update record event to use new Trace ID protocol
Trace IDs are now dynamically allocated. Previously used the static association algorithm that is no longer used. The 'cpu * 2 + seed' was outdated and broken for systems with high core counts (>46). as it did not scale and was broken for larger core counts. Trace ID will now be sent in PERF_RECORD_AUX_OUTPUT_HW_ID record. Legacy ID algorithm renamed and retained for limited backward compatibility use.
