This PR provides some infrastructure that I think is missing and would be nice using in #49138

With this patch, if an `HttpException` is thrown and if it wraps either a `ValidationFailedException` or a `PartialDenormalizationException`, Symfony will return a JSON containing the details of the validation failures / missing properties when the request comes with `Accept: application/json`.

I also fixed a few minor things that I found while digging the code on this topic.
