KIP-730 — Producer ID generation in KRaft mode

Accepted Kafka 3.0 KRaftTransactions

Replaces the ZooKeeper-based block allocation scheme for producer IDs with a KRaft controller-managed `AllocateProducerIds` RPC, where brokers request blocks of IDs from the active controller. Without this, EOS and idempotent producers cannot function in a fully ZooKeeper-free KRaft cluster.
