KIP-673 — Emit JSONs with new auto-generated schema

Accepted Kafka 2.8 ProtocolBroker

Extends Kafka's request/response debug logging (`RequestChannel`) to emit structured JSON using the auto-generated `*JsonConverter` classes (e.g., `FetchRequestDataJsonConverter`) instead of the existing pseudo-JSON format. The existing log format is not valid JSON and cannot be reliably parsed by tools like `jq`, Elasticsearch, or Druid, limiting its utility for request tracing and analysis.
