[Enhancement] Load balancing cache in POP consumption mode

[YoWuwuuuw]

Which Issue(s) This PR Fixes

Add cache for each client request broker end rebalancing in the pop consumption mode to avoid wasting computing resources of broker end due to repeated calculation of load balancing without changes. The effect is more obvious in theory when there are a large number of queues or consumers

Fixes #9123

Brief Description

1. Cache location: Add cache before the rebalancing distribution queue
2. Cache logic: Since only the number of consumer groups, the number of queues and clientId can affect the rebalancing calculation, the topic is used as the first layer cache key, and the clientId is used as the second layer cache key, and the consumer groups and queues of the topic are stored as the verification basis
3. Cache hit: The topic exists in the cache, and the number of consumer groups and queues remain the same as before
4. Cache update: When the cache is not hit, the cache is updated after the rebalancing calculation
5. Details: Use reentrant lock to maintain consistency and efficiency, set 24-hour clean-up thread to clean up the cache, and prevent the cache from failing due to the offline of topics

How Did You Test This Change?

Ten consumers were registered for the test consumer group, and mock 15 queues were set up to test the correctness and performance of the broker-end doLoadBalance method under the test pop consumption mode. All QueryAssignmentProcessorTest (including the original 5 methods) passed, and the performance is as follows (in the local environment)

The cache should be updated when the client is offline or the number of queues changes, but I don't see the logic for that

When the number of clients changes or the number of queues changes.Should clear cache

Ok, I've added a cleanup thread for PopCacheManager and tested it to completely clear the cache every 24 hours (the cache expiration only happens when the topic goes offline, and I'll modify "Brief Description" to simply explain the cache logic). This cleanup interval can be added to the configuration if needed later
