KIP-748 — Add Broker Count Metrics

Accepted Kafka 3.1 MetricsKRaft

Introduces two new KRaft controller metrics: `ActiveBrokerCount` (registered, unfenced brokers) and `FencedBrokerCount` (brokers that registered but are fenced). Without these metrics, a broker that is alive but failing to emit metrics or logs is indistinguishable from a broker that never registered, making cluster health assessment unreliable.
