[RFC PATCH v2 12/14] perf stat: Extend JSON output linter to test advanced PMU and metric-only checks

[Ian Rogers]

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

  - check_per_cache_instance
  - check_per_cluster
  - check_metric_only

This guarantees that JSON outputs produced by the decoupled streaming printing callbacks
are verified and structurally valid under advanced topology-aware modes and metric-only
JSON row-column layouts.
