Subject: [PATCH] [fix](JDK17) The objects stored in `PriorityQueue` must
 implement the `Comparable` interface (#30050) (#30625)

Issue Number:  #30484

The objects stored in PriorityQueue must implement the Comparable interface or passed into the customized `Comparator`.

If we don't do this, run the program in the JDK17 environment will report an exception:
```java
Caused by: java.lang.AssertionError: Expect exception msg contains 'query wait timeout', but meet
'java.sql.SQLException: ClassCastException,
msg: class org.apache.doris.resource.workloadgroup.QueueToken cannot be cast to class java.lang.Comparable
(org.apache.doris.resource.workloadgroup.QueueToken is in unnamed module of loader 'app'; java.lang.Comparable is in module java.base of loader 'bootstrap')'
```
