[PATCH v2 9/9] perf vendor events: Update metrics to detect optane memory at runtime

From: Ian Rogers
Date: Thu Mar 23 2023 - 15:22:50 EST

By detecting whether optane memory is installed at runtime the number
of events can be reduced if it isn't. These changes come from this PR:
https://github.com/intel/perfmon/pull/63
