[BugFix] fix broker load job hang when meet resource group pending timeout (backport #51072)

[mergify]

Why I'm doing:

In previous PR #38183, we will skip cancel loading job when timeout happen. But when broker load met resource group pending timeout like:

com.starrocks.common.UserException: Failed to allocate resource to query: pending timeout [300], you could modify the session variable [query_queue_pending_timeout_second] to pending more time
at com.starrocks.qe.QueryQueueManager.maybeWait(QueryQueueManager.java:81) ~[starrocks-fe.jar:?]
at com.starrocks.qe.DefaultCoordinator.startScheduling(DefaultCoordinator.java:488) ~[starrocks-fe.jar:?]
at com.starrocks.qe.scheduler.Coordinator.startScheduling(Coordinator.java:102) ~[starrocks-fe.jar:?]
at com.starrocks.qe.scheduler.Coordinator.exec(Coordinator.java:85) ~[starrocks-fe.jar:?]

It's not a loading job timeout, but because error message contains timeout, so we will consider it as normal timeout and won't cancel it immediately, so load job will hang until timeout happens.

What I'm doing:

When we met resource group pending timeout, we can set it as USER_CANCEL, so we can cancel it immediately.
