  -----------
  [ORC] Generalize materialization dispatch to task dispatch.

Generalizing this API allows work to be distributed more evenly. In particular,
query callbacks can now be dispatched (rather than running immediately on the
thread that satisfied the query). This avoids the pathalogical case where an
operation on one thread satisfies many queries simultaneously, causing large
amounts of work to be run on that thread while other threads potentially sit
idle.

  Log Message:
  -----------
  [ORC] Use the new dispatchTask API to run query callbacks.

Dispatching query callbacks, rather than running them on the current thread,
will allow them to be distributed across multiple threads.
