### Before Creating the Enhancement Request - [X] I have confirmed that this should be classified as an enhancement rather than a bug/feature. ### Summary Make `NotificationProcessor` use `PopLongPollingService` ### Motivation 1. Use a unified class `PopLongPollingService` to implement long-polling. 2. The original `wakeup` in `NotificationProcessor` will notice all the long-polling requests with same key. 3. The `polling` method in `NotificationProcessor` has a potential data race condition. https://github.com/apache/rocketmq/blob/d9223ffd787099285cb728d176a05795f6f56df6/broker/src/main/java/org/apache/rocketmq/broker/processor/NotificationProcessor.java#L301-L308 ### Describe the Solution You'd Like 1. Move long-polling related code from `PopMessageProcessor` into `PopLongPollingService` like `wakeup()` 2. Use `PollingResult` enum to replace int value 3. `NotificationProcessor` use `PopLongPollingService` to implement long-polling. ### Describe Alternatives You've Considered No ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
