KIP-797 — Accept duplicate listener on port for IPv4/IPv6

Accepted Kafka 3.6 Broker

Loosens listener validation to permit two listeners on the same port when one is IPv4 and the other is IPv6, both specified as IP literals. Previously Kafka rejected any duplicate port in the listener configuration regardless of the address family, making it impossible to bind the same port on both 0.0.0.0 and :: without using the wildcard form.
