Update Client- and Wallet Metadata

[JoTiTu]

Short description of what this resolves:

• Add encrypted_response_enc_values_supported (authorization_encrypted_response_enc kept for backwards compatibility)
• Add vp_formats_supported (vp_formats kept for backwards compatibility), update the properties for mso_mdoc and add vp_formats_not_supported error code
• Refactor WalletMetadata

    var list = enumerable.ToList();
    return list.IsEmpty()
        ? Option<IEnumerable<T>>.None
        : list;

The tests are too opinionated and also too coupled to implementation details => I dont care if the function returns true or false, i care about if the program behaves correctly given the respective input (valid vp formats => can parse client metadata, invalid formats => cant parse clientmetadata).

Missing parsing test

[JoTiTu]

It's already part of the AuthRequest parsing test. I think as long as we have not migrated the whole AuthRequest Parsing to proper Validation it doesn't add a lot of value, no?
