ssh: allow server auth callbacks to send additional banners

Add a new BannerError error type that auth callbacks can return to send
banner to the client. While the BannerCallback can send the initial
banner message, auth callbacks might want to communicate more
information to the client to help them diagnose failures.

Updates golang/go#64962
