Re: [webauthn] Consider RP ID migration use cases (#2350)

IMO, this is already possible today:

- Related Origin Requests gives you access to the "old" passkey on the new origin.
- Conditional Create allows you to automatically create a "new" one after a sign in with the "old" one
- Signal API allows you to clean up the old passkey, via an iframe (although we could probably enhance this to use the ROR origin list to allow cross-origin cleanup without the iframe)

What's missing from this combo?
