innodb_fast_shutdown=0 can be unnecessarily slow

Details

    Description

      Now that MDEV-16264 replaced the InnoDB purge threads with tasks, it should be possible to increase the purge effort during a slow shutdown (while innodb_fast_shutdown=0 is in effect). Currently, we are using the fixed amount of innodb_purge_threads also during shutdown, even if the server were mostly idle.
