[RFC PATCH v2 09/14] perf stat: Extend CSV output linter to test advanced PMU and metric-only checks

[Ian Rogers]

This patch extends tools/perf/tests/shell/stat+csv_output.sh to run
the advanced hardware PMU, topology-aware aggregation, and metric-only
checks a second time under the --new CSV print flag:

  - check_per_cache_instance
  - check_per_cluster
  - check_metric_only

This guarantees that CSV outputs produced by the decoupled printing callbacks
are verified and column-valid under advanced aggregation modes and metric-only
CSV row-column layouts.
