Actually, I think, better approach may be to have a special `StepElementsAttr` in the same way we already have `SplatElementsAttr`, which is "canonicalized" on `DenseElementsAttr` construction like `SplatElementsAttr`. This way we don't need any special ops and users which doesn't know or doesn't care about `StepElementsAttr` can still work with it as normal dense constant.
