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

I'd like to clarify that this is mostly orthogonal, as far as I'm concerned.

The main issue here is figuring out how to ensure that a new browser profile can get an associated registration for an RP while keeping the process as straightforward as possible for the user (i.e. by handling it all in a single prompt, if possible). Until something like #1545 becomes available, there is no way for the RPs to do anything without potential situations where a prompt is guaranteed to lead to an error even in the "happy path".

This is already an issue for authenticators/browsers that support discoverable credentials (notably, Safari and Windows Hello). Discoverable credentials in Android would be very welcome, but would not directly help with this issue.

I realized recently that a potential point of confusion is that we want GitHub to support UVPA trusted devices for users without "normal 2FA". My comment here might help clarify some things: https://github.com/w3c/webauthn/issues/1566#issuecomment-782444786
