Subject: [PATCH v1 13/22] perf vendor events: Update Icelake events/metrics
Update events from v1.22 to v1.24.
Update TMA metrics from 4.8 to 5.01.
Bring in the event updates v1.24:
https://github.com/intel/perfmon/commit/d4f10746cf549466723d17cd214e1ee9cb7bac11
The TMA 5.01 update is from (with subsequent fixes):
https://github.com/intel/perfmon/commit/1d72913b2d938781fb28f3cc3507aaec5c22d782
