Update Tomcat, Jetty, Undertow and Netty servers so that an SslBundle is used to apply SSL configuration. Existing `Ssl` properties are internally adapted to an `SslBundle` using the `WebServerSslBundle` class. Additionally, if `Ssl.getBundle()` returns a non-null value the the `SslBundles` bean will be used to find a registered bundle by name. See gh-34814
