Take response status of aborted request into account in JAX-RS Client

Fixes: #22827

@geoand Thank you very much for this fix! Alas, as far as I can tell, there are two kinds of reponse information this fix does not include: the status reason phrase and the entity, both of which could contain helpful information. What do you think about setting the entity via setExistingEntity on status 0 detection? Also, the reasonPhrase in the WebClientApplicationException constructor should be extracted from the aborted Response in those cases: requestContext.getAbortedWith().getStatusInfo().getReasonPhrase(). Of course, this implies further refactorings, unfortunately.

You can certainly open a draft PR with the proposed suggestion

I will give it a try, it could take some time, though
