Gian Merlino 77297f4e6f GroupBy array-based result rows. (#8196) 
* GroupBy array-based result rows.

Fixes #8118; see that proposal for details.

Other than the GroupBy changes, the main other "interesting" classes are:

- ResultRow: The array-based result type.
- BaseQuery: T is no longer required to be Comparable.
- QueryToolChest: Adds "decorateObjectMapper" to enable query-aware serialization
  and deserialization of result rows (necessary due to their positional nature).
- QueryResource: Uses the new decoration functionality.
- DirectDruidClient: Also uses the new decoration functionality.
- QueryMaker (in Druid SQL): Modifications to read ResultRows.

These classes weren't changed, but got some new javadocs:

- BySegmentQueryRunner
- FinalizeResultsQueryRunner
- Query

* Adjustments for TC stuff.
