KIP-934 — Add DeleteTopicPolicy

Discussion BrokerAdmin

Introduces a `DeleteTopicPolicy` plugin interface (analogous to `CreateTopicPolicy` from KIP-108) that brokers invoke before executing a topic deletion to allow operators to veto or control the deletion. Without a deletion policy, operators have no server-side safeguard to prevent accidental deletion of critical internal topics (e.g., `__consumer_offsets`, Connect internal topics) even when coarse-grained ACLs grant delete permission.
