KAFKA-12738: send LeaveGroup request when thread dies to optimize replacement time (#11801) 

Quick followup to #11787 to optimize the impact of the task backoff by reducing the time to replace a thread. When a thread is going through a dirty close, ie shutting down from an uncaught exception, we should be sending a LeaveGroup request to make sure the broker acknowledges the thread has died and won't wait up to the `session.timeout` for it to join the group if the user opts to `REPLACE_THREAD` in the handler
