Merge #21016: refactor: remove boost::thread_group usage

dc8be12510 refactor: remove boost::thread_group usage (fanquake)

Pull request description:

  Post #18710, there isn't much left using `boost::thread_group`, so should just be able to replace it with the standard library. This also removes the last use of `boost::thread_interrupted`.

  After this change, last piece of Boost Thread we'd be using is `boost::shared_mutex`. See the commentary [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) as to why it may be non-trivial to swap that for `std::shared_mutex` in the near future.

  Closes #17307
