Re: [webauthn] U2F Attestation only lists Basic Attestation as supported

Now the spec instead doesn't say how to detect when the `fido-u2f` attestation statement format uses self attestation. It seems like that would be when `attStmt.x5c[0]` is self-signed, correct? Either way I think the verification procedure in [§7.6][1] should make some mention of self attestation, as currently

- the only occurence of the word "self" in §7.6 is in the list of supported attestation types; and
- the final step of the verification procedure says to always return attestation type Basic. While this is technically correct as the returned `x5c` is indeed the entire trust path, it is confusing.
