[CSSPGO][SCCIterator] Fix a non-determinism in scc_member_iterator
Previously we initialed the work queue with MST roots based on NodeInfoMap which is an unordered map. This could cause a non-determinism. I'm fixing this by initializing the queue based on SortedEdges.
I don't see any performance move with this change. However this helps debugging.
