    gprofng: add hardware counters for AMD Zen3

    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.
