webauthn: split up 410 and linking callbacks.

Information flowing from caBLEv2 tunnels to the authentication request
delegate is currently contained in a single callback which takes an
`absl::variant` of the possible events.

In order to allow linking information to be received after a transaction
is complete, linking events will have to be processed after the
destruction of the delegate, but invalid-tunnel events still want to be
processed within the delegate as they continue to be lifetime-bounded in
the obvious way.

This change splits the current callback into two callbacks so that it's
easier to route the events to different places for handling. Currently
this is a no-op, however.
