Add original item totals for cart refresh

[pepijn-vanvlaanderen]

Summary

What — What changes are introduced in this PR?

Added original_item_total & original_item_subtotal on the cartFieldsForRefreshSteps. So it can be used eventually as a promotion rule.

Why — Why are these changes relevant or necessary?

Currently the original item totals are not passed in the cart workflow on updateCartPromotionsWorkflow. So you could only restrict with item_total, which is not convenient, since after the discount is applied this value is impacted.

How — How have these changes been implemented?

Added original_item_total & original_item_subtotal on the cartFieldsForRefreshSteps.

Testing — How have these changes been tested, or how can the reviewer test the feature?

Added this change as a patch on our project(s) and have a working promotion rule value where attribute is original_item_total.
