Update ShapeCastOp folder to use producer-consumer value forwarding.
Support is added for tracking sub-vectors through trivial shape cast operations,
where the sub-vector shape is preserved across shape cast operations and only
leading ones are added or removed.
Support is preserved for cancelling shape cast operations.
One unit test is added and two are updated.
