KIP-578 — Add configuration to limit number of partitions

Discussion BrokerAdmin

Introduces `max.partition.count` broker and per-topic configuration limits that the broker enforces on `CreateTopics` and `CreatePartitions` requests to prevent partition counts from exceeding safe operational thresholds. Without enforcement, operators can create topics with partition counts that cause live-locked clusters where even remediation (topic deletion) becomes unresponsive.
