KIP-1216 — Add rebalance listener metrics for Kafka Streams

Accepted Kafka 4.2 StreamsMetrics

Adds tasks-revoked-latency, tasks-assigned-latency, and tasks-lost-latency (avg + max) metrics for the Kafka Streams rebalance listener callbacks under the new KIP-848 streams rebalance protocol. Streams migrated from the consumer rebalance listener to a streams-specific implementation, dropping the latency metrics that previously existed for revoked/assigned/lost partition callbacks.
