The interface org.springframework.boot.web.server.WebServer defines that getPort() returns -1 if the server isn't listening on a port. This commit changes the implementations of the interface accordingly. See spring-projectsgh-24540

Update `WebServer` implementations to return -1 from `getPort()` if the server isn't listening on a port. This aligns the implementations with the interface Javadoc. See gh-24606

The interface
org.springframework.boot.web.server.WebServerdefines thatgetPort()returns-1if the server isn't listening on a port. But the current implementations of the interface return 0 instead. This changes the implementations to return -1.Please note: Jetty itself does return -2 as the local port after the connection has been closed. Therefore in its implementation getPort() maps all local ports <= 0 to -1 to match the method's contract.
