Re: [webauthn] Refine JSON serialization to use UTF-8 encoding for `user.id` and `userHandle` (#2013)

A side effect of this change might be that RP's feel empowered to use PII-containing identifiers here since they're already strings. However I think we could easily enough suggest base64url-encoding 64 random bytes and then using that string as `user.id` when calling `parseCreationOptionsFromJSON()` and the user privacy considerations in https://w3c.github.io/webauthn/#sctn-user-handle-privacy are maintained.
