Optimize HpcOmTaskGraph.createTaskGraph (#12905)

- Move the sorting of the graph to `createTaskGraph0` once the graph is
  completed instead of doing it for each component in
  `createTaskGraph1`, since `createTaskGraph1` only adds nodes.
- Use `Array.mapNoCopy` instead of `Array.map1` when doing the sorting
  since we don't need to copy the array.
