Missing HttpChannel.Listener.onResponseTrailers(Request)

[joakime]

Jetty version
9.4.29

Description
In the process of implementing ByteCount API for Issue #4954 it was discovered that there is no Response equivalent for the HttpChannel.Listener.onRequestTrailer(Request request) method.

https://github.com/eclipse/jetty.project/blob/77c232aed8a45c818fd27232278d9f95a021095e/jetty-server/src/main/java/org/eclipse/jetty/server/HttpChannel.java#L1095-L1102

We should add a HttpChannel.Listener.onResponse(Request request) method.

@lorban can you check what's the status of this issue in Jetty 12?

The 12.0.x EventsHandler has a void onResponseTrailersComplete(Request request, HttpFields trailers) event that should cover this.
