Vectorized versions of HllSketch aggregators. (#11115)
* Vectorized versions of HllSketch aggregators.

The patch uses the same "helper" approach as #10767 and #10304, and
extends the tests to run in both vectorized and non-vectorized modes.

Also includes some minor changes to the theta sketch vector aggregator:

- Cosmetic changes to make the hll and theta implementations look
  more similar.
- Extends the theta SQL tests to run in vectorized mode.

* Updates post-code-review.

* Fix javadoc.
