Re: [webauthn] Rework the FIDO AppID extension.

I think the format difference between the two won't matter in practice - except perhaps in how the client stores them internally, as @agl pointed out. But for interop purposes it should make no difference: The client will have both the RP ID and the AppID; non-U2F authenticators will get the RP ID as usual (and will never see a FIDO AppID); and U2F authenticators will get the SHA256 hash of the AppID and won't actually see the underlying AppID.
