[ISSUE #9699] Optimize shutdown process and resource management (#9700)

* Optimize shutdown process and resource management

- Improve BrokerController shutdown flow for graceful shutdown
- Optimize BrokerStartup startup and shutdown logic
- Enhance ClientHousekeepingService resource cleanup
- Improve shutdown handling for various processors
- Optimize resource management in storage layer components
- Enhance lifecycle management for statistics manager
- Improve shutdown flow for timer components

* Fix this.popMessageProcessor.getPopLongPollingService() not shutdown

* Fix test shutdown state transition issue

- Add proper null checks and exception handling in test cleanup
- Prevent IllegalStateException during test teardown
- Ensure graceful test cleanup without state conflicts

* Fix DefaultMessageStoreCleanFilesTest can not pass

* Fix CombineConsumeQueueStoreTest can not pass

* Polish the code

* Polish the code

* Ignore flaky test first
