hoist static_key_apply_queued from ddebug_change to exec_queries. This can reduce IPIs when multiple queries are submitted together in the same command-buffer, as when they're separated by by \n ; or %. It won't affect single command submissions, or settings of class-map-params, which are submitted 1 bit at a time.
