MLBEDSW-11223: Fix slice-handling in ReshapeElementwise
- ReshapeElementwise supports slices as long as the slice-volume represents the whole tensors. Such slices can be removed safely, which simplifies slice maintenance.
- Fix bug in hasSlices condition
- Add hasStride condition as we cannot reshape strided slices.
