Update codegeneration of redefined properties

[samatstariongroup]

according to the KerML spec:

A model element maps to a JSON Schema object with fields @id, @type, and a set of its attributes. The field @id
has a string value equal to the value of Element::elementId. The field @type has a string value equal to the
name of the specific MOF type of the element, e.g. "Structure".

The remaining JSON Schema fields are mapped from the set of MOF properties specified as attributes of the MOF
type of the element. This shall include all owned and inherited properties. **In addition, while redefined properties are
not inherited under MOF/UML rules, they shall be included in the set of properties serialized for the element if they
have a different name than the redefining property**.

this means that DTO generation and JSON serialization need to be updated to accomodate this
