Spring JettyHttpHandlerAdapter is not aware of Server[Request|Response]Wrapper

Affects: 5.3.7

In JettyServerHttpRequest#createHeaders, it is assumed that the given HttpServletRequest is a org.eclipse.jetty.server.Request, while it could be a HttpServletRequestWrapper. Similarly, JettyServerHttpResponse#createHeaders assumes that the given response is a org.eclipse.jetty.server.Response, while it could be a HttpServletResponseWrapper.

Similar to https://github.com/spring-projects/spring-framework/issues/22143, but just for Jetty.
