When I replaced #604 with #626, I botched extracting this part of the code. I had the trait, which taught kaguya how to serialize `PossiblyKnownTagValue`, but I missed updating the parameter type of `Attribute` to actually use it, so it was a no-op. This PR restores the behaviour of avoiding string copies, but now that we have protozero's data_view class, we can use that rather than our own weirdo struct.
