This commit ensures that Tomcat is the first reactive server configured if the Tomcat dependency is on classpath. Spring Boot chose Reactor Netty as the default for the reactive web starter, but the Reactor Netty dependency can be used also for its HTTP client. In case developers are adding Tomcat, Undertow or Jetty on their classpath, we must configure those and consider Reactor Netty for the client only. Fixes gh-12176
