Start using value inference in constant value inference.

- Change rest of the kernels that support dynamic shapes to use value inference.
- Update pad_op so that it can infer a tigher bound using value inference.
- Update slice_op so it doesn't create a shape with all dynamic dimensions when some slice sizes are constant.
