dynamic_modules: expose stat tags and tag-extracted names in the stats sink ABI
Commit Message: expose stat tags and tag-extracted names in the stats sink ABI
Additional Description:The stats sink ABI previously exposed only each stat's full, flat name (e.g. cluster.foo.upstream_rq_total) and its value. This adds callbacks to also read a stat's tag-extracted name and its tags (name/value pairs) for counters, gauges, etc.
This lets a custom dynamic-module stats sink consume the same dimensional decomposition Envoy's built-in formatters use so it can reconstruct labelled output like envoy_cluster_upstream_rq_total{cluster_name="foo"} instead of only the flat name.
