Re: [webauthn] Support a "create or get [or replace]" credential re-association operation (#1568)

> App can always send all the known credentialID in excludeList and credential will not be overwritten.

How can `excludeCredentials` work with residential/discoverable keys and without username? The whole idea is that without username, I do not know in advance which keys the user has, so I cannot use `excludeCredentials`. If I do `get` and user aborts, then I might prompt the user to register a key, but if they make a mistake and do register a key, it will override any existing key.
