Build failed, because we have Clang13 in master, but 21.9 builds successfully only with Clang11. I think we have to merge it, and maybe fix tests in 21.9 branch directly. |

Backport of #29544
Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):
Avoid deadlocks when reading and writting on JOIN Engine tables at the same time
Detailed description / Documentation draft:
Manual backport of #29544 to 21.9 since there were some conflicts and automatic backport didn't work. The idea is to backport it to other stable releases as long as it doesn't require many tweaks on top of the original PR.
Tested by adding the test (
./tests/clickhouse-test 02033_join_engine_deadlock_long) and running it before the changes (blocks and doesn't finish) and after (finishes normally).It's a backport, but tagging it as a bug fix since the CI asks for a description.
