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:

Some Intel TMA metrics compute a ratio that may divide by 0, which
causes the metric not to print. This happens for metrics with FP_ARITH
events. If we see these events in the result and would otherwise fail,
then switch to a skip.
Also, don't early exit when processing metrics.

Test every metric and metricgroup with 'true' as a workload. For
metrics, check that we see the metric printed or get unsupported. If the
'true' workload executes too quickly retry with 'perf bench internals
synthesize'.
v3. Fix test condition (thanks to Paul A. Clarke <pc@us.ibm.com>). Add a
fallback case of a larger workload so that we don't ignore "<not
counted>".
v2. Switched the workload to something faster.
