Lang Hames 5344c88dcb [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.
