[recipe_wrapper] Use attestation repo structs from protos
This change modifies the internal handling of the input data to the attestation tool to use a struct generated from the official in-toto repository. This should help ensure that the specification is truly matched. Unfortunately, the predicate struct itself (which contains the SLSA build information) is dynamically typed, but all that stuff is basically metadata which isn't used for attestation, anyway.
