Order Skyframe evaluations in a priority queue, with all children of a given node having the same priority, later enqueueings having higher priority, re-enqueued nodes having highest priority, and new root nodes having lowest priority. Experimentally, this can save significant RAM (1.4G in some builds!) while not affecting speed.

Also do a semi-drive-by deleting ExecutorFactory parameter to AbstractQueueVisitor, since it was always AbstractQueueVisitor.EXECUTOR_FACTORY.
