GH-9623: Fix ThreadStatePropagationChannelInterceptor for concurrency

Fixes: #9623
Issue link: #9623

The `ConcurrentModificationException` is thrown from the `ThreadStatePropagationChannelInterceptor.MessageWithThreadState.stateQueue`
which is a not thread-safe `LinkedList`

* Fix `ThreadStatePropagationChannelInterceptor.MessageWithThreadState.stateQueue` to be a `LinkedBlockingQueue` instead

**Auto-cherry-pick to `6.3.x` & `6.2.x`**
