Jetty 12.0.x 10582 servlethttpwrapper

Closes #10582

[gregw]

We now need a specific test to check that we can handle non HTTP Servlet wrappers for request and response.

P.S. we can probably squeak this into 12.0.2 if it is ready soon

I want to see:

Suggested change

	HttpServletRequest wrappedRequest = new ServletRequestHttpWrapper(request);
	HttpServletResponse wrappedResponse = new ServletResponseHttpWrapper(response);
	chain.doFilter(wrappedRequest, wrappedResponse);
	chain.doFilter(new ServletRequestWrapper(request), new ServletResponseWrapper(response));
