Allow the gRPC extension to be used with Jetty 12

[leeturner]

Proposal

At the moment, the gRPC extension is tied to the Jetty11HttpServer in the buildHttpServer method.

@Override
  public HttpServer buildHttpServer(
      Options options,
      AdminRequestHandler adminRequestHandler,
      StubRequestHandler stubRequestHandler) {
    return new Jetty11HttpServer(options, adminRequestHandler, stubRequestHandler) {
      @Override
      protected void decorateMockServiceContextBeforeConfig(
          ServletContextHandler mockServiceContext) {

        final GrpcFilter grpcFilter = new GrpcFilter(stubRequestHandler, fileDescriptors);
        final FilterHolder filterHolder = new FilterHolder(grpcFilter);
        mockServiceContext.addFilter(filterHolder, "/*", EnumSet.of(DispatcherType.REQUEST));
      }
    };
  }

This means it won't work anywhere where we need to rely on Jetty12 like the 3.x.x releases of Spring Boot. It would be nice to support both Jetty 11 and 12 like we do in WireMock core

Is there any follow-up on this? Any plans to enable gRPC on Jetty 12?
