perf test: Make all metrics test more tolerant

Browse Source 
Metric names are truncated so don't try to match all of one.

Allow AMX metrics to skip as floating point ones do.

Metrics for optane memory can also skip rather than fail.

Add a system wide check for uncore metrics.

Restructure code to avoid extensive nesting.

Some impetus for this in:
