Historically, we have used several APIs (perfctr, libcpc, perf_event_open) for profiling.
For each hardware we have several tables of hardware counters.
Some information is duplicated in these tables.
Some of the information is no longer used.
I did not touch the existing hwc tables.
I added a new hwc table for an AMD Zen3 machine.
