Jordan Rose 70ec1ca26f zkgroup: Add AuthCredentialWithPni
This is a variant of AuthCredential that carries two UUIDs, intended
to be a user's ACI and PNI. Why? Because when you've been invited to a
group, you may have been invited by your ACI or by your PNI, or by
both, and it's easier for clients to treat all those states the same
by having a credential that covers both identities. The downside is
that it's larger (both the data, obviously, but also the zkgroup proof
of validity, unsurprisingly).

AnyAuthCredentialPresentation gains a 'get_pni_ciphertext' method,
which will return `None` for the existing presentations and
`Some(encrypted_pni)` for the new credential. Having a separate
credential type but a common presentation type makes it easier for the
server to handle all possible credentials uniformly.
