[c10d] Enforce order of waited ranks in monitored barrier. (#55009) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/55009 Changes monitoredBarrier so that we await acknowledgemenet from ranks in a consistent order (from least to greatest). This will reduce confusion around the order the ranks are awaited. We are still planning to add support for awaiting all ranks in follow up changes. ghstack-source-id: 125699838 Test Plan: CI Reviewed By: SciPioneer Differential Revision: D27405417 fbshipit-source-id: b9a3e72742cbffdd9bf890ab2c94103b768a7b71
