Which Issue(s) This PR Fixes

Fixes #8942

• Add incGroupAckNums and incGroupCkNums to LmqBrokerStatsManager
• Add a setBrokerStatsManager method to enhance extensibility, allowing for more fine-grained control to be implemented externally. Alternatively, we could discuss the removal of the LmqBrokerStatsManager class, as it appears to have limited value in my opinion.
