We have a lot of native contract types that are converted to stack items before serialization, then deserialized as stack items and converted back to regular structures. stackitem.Convertible allows to remove a lot of repetitive io.Serializable code. This also introduces to/from converter in testserdes which unfortunately required to change util tests to avoid circular references.
