  -----------
  [mlir][mesh] adding option for traversal order in sharding propagation (#144079)

The traversal order in sharding propagation was hard-coded. This PR
provides options to the pass to select a suitable order
- forward-only
- backward-only
- forward-backward
- backward-forward

Default is the previous behavior (backward-forward).
