Propagate sort instrumentation from workers back to leader. Up until now, when parallel query was used, no details about the sort method or space used by the workers were available; details were shown only for any sorting done by the leader. Fix that.
Commit 1177ab1dabf72bafee8f19d904cee3a299f25892 forced the test case added by commit 1f6d515a67ec98194c23a5db25660856c9aab944 to run without parallelism; now that we have this infrastructure, allow that again, with a little tweaking to make it pass with and without force_parallel_mode.
