[Config] Create XML Reference Dumper

Only Yaml was supported. This PR adds support for XML. This makes it easier to test XML schema's (see symfony-cmf/MenuBundle#114 ), helps us at the docs with our configuration reference and helps others using XML with symfony.

## Todo

 - [x] Prototyped arrays don't work properly
 - [x] Add comments (see Yaml dumper)
 - [x] Add namespaces support

## Side effects

I've moved the reference dumpers to their own namespace and renamed the original reference dumper to `YamlReferenceDumper`. The old one is kept for BC, but deprecated.

The rationale behind this PR is to be able to use any of the sub components without requiring all the dependencies of the other sub components. Specifically, I'd like to use the core utils for an improved CSRF protection mechanism (#6554).
