Re: [webauthn] Add `challengeUrl` (#2152)

Why do challenges need to be fetched from the server? Couldn't the challenge also be generated client-side? The client would then send both `AuthenticationResponseJSON` and the base64url-encoded challenge to the server? This would reduce latency even further. Is the idea that mobile devices are not powerful enough to generate 16 bytes of entropy for the challenge?
