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.

PR gprofng/31123
* common/core_pcbe.c (core_pcbe_get_events): Add new argument.
* common/hwc_cpus.h: New constants for AMD hardware.
* common/hwcdrv.c: Add new argument to hwcdrv_get_descriptions.
Clean up the code.
* common/hwcdrv.h: Likewise.
* common/hwcfuncs.c (hwcdrv_get_descriptions): Add new argument.
* common/hwctable.c: Add the hwc table for AMD Zen3.
* src/hwc_amd_zen3.h: New file.
* common/opteron_pcbe.c: Add new argument to opt_pcbe_get_events.
* src/collctrl.cc: Remove unused variable.
* src/collctrl.h: Likewise.
