Re: [webauthn] Add Changed Flag to UVM Entry (#1890)

The `uvi` extension (along with several others) was indeed removed from L2 and L3 of the spec, and indeed due of lack of implementations. But they are all still registered in the authoritative [IANA registry](https://www.iana.org/assignments/webauthn/webauthn.xhtml#webauthn-extension-ids), so there's nothing stopping clients and authenticators from implementing support for them. But extensions are by design optional to implement, so we cannot in this spec mandate that clients or authenticators implement them.
