[0/4] perf vendor events arm64: AmpereOne: Core PMU event update and metrics

Message

AmpereOne Core PMU documentation had unsupported events listed, which have
been removed since. In addition, certain STALL_* events have a bug and,
thus, the errata number is added for reference. Finally, metrics are added
for AmpereOne.
