quic: set ServerName in client connection TLSConfig

Client connections must set tls.Config.ServerName to authenticate
the identity of the server. (RFC 9001, Section 4.4.)

Previously, we specified a single tls.Config per Endpoint.
Change the Config passed to Listen to only apply to
client connections accepted by the endpoint.
Add a Config parameter to Listener.Dial to allow specifying a
separate config per outbound connection, allowing the user
to set the ServerName field.

When the user does not set ServerName, set it ourselves.

For golang/go#58547
