  [orc-rt] Refactor QueueingTaskDispatcher to use an external TaskQueue. (#190920)

QueueingTaskDispatcher now takes a TaskQueue by reference rather than
maintaining an internal queue. This lets API clients retain direct
access to the queue after transferring dispatcher ownership to the
Session.

TaskQueue operations (takeFirstIn, takeLastIn) are blocking: callers
wait until a task arrives or the queue is shut down. This enables a
simple client idiom:

```
  QueueingTaskDispatcher::TaskQueue TQ;
  Session S(std::make_unique<QueueingTaskDispatcher>(TQ), ...);
  S.attach(<controller access>);

  while (auto T = TQ.takeFirstIn())
    T->run();
```
