Convert hashSets in parallel before merge (#50748) 
* Convert hashSets in parallel before merge

Before merge, if one of the lhs and rhs is singleLevelSet and the other is twoLevelSet,
then the SingleLevelSet will call convertToTwoLevel(). The convert process is not in parallel
and it will cost lots of cycle if it cosume all the singleLevelSet.

The idea of the patch is to convert all the singleLevelSets to twoLevelSets in parallel if
the hashsets are not all singleLevel or not all twoLevel.

I have tested the patch on Intel 2 x 112 vCPUs SPR server with clickbench and latest upstream
ClickHouse.
Q5 has got a big 264% performance improvement and 24 queries have got at least 5% performance
gain. The overall geomean of 43 queries has gained 7.4% more than the base code.

ClickHouse performance tests

This directory contains .xml-files with performance tests for @akuzm tool.

How to write performance test

First of all you should check existing tests don't cover your case. If there are no such tests than you should write your own.

You can use substitions, create, fill and drop queries to prepare test. You can find examples in this folder.

If your test continued more than 10 minutes, please, add tag long to have an opportunity to run all tests and skip long ones.

How to run performance test

TODO @akuzm

How to validate single test

pip3 install clickhouse_driver scipy
../../docker/test/performance-comparison/perf.py --runs 1 insert_parallel.xml
