Kafka 内存池MemoryPool 设计

GarbageCollectedMemoryPool 是一个非常巧妙的调试工具。它通过继承 SimpleMemoryPool 复用了内存额度控制的逻辑，然后通过重写钩子方法和结合Java的引用机制，增加了一层“内存泄漏”的监控。

正常流程：tryAllocate() -> bufferToBeReturned (登记) -> 使用 -> release() -> bufferToBeReleased (注销) -> ByteBuffer 失去引用 -> 被GC。
泄漏流程：tryAllocate() -> bufferToBeReturned (登记) -> 使用 -> 忘记调用 release() -> ByteBuffer 失去引用 -> 被GC -> BufferReference 进入队列 -> 后台线程检测到，并从 buffersInFlight 中找到了登记信息 -> 报告错误。
