Pass $parser, &$query and &$widthOption to the 'ImageBeforeProduceHTML' hook

This allows extensions to essentially reimplement Linker#makeImageLink
completely. Before this wasn't 100% possible as these three are needed for
that.

Inspired by wikiHow's core hacks to /includes/Linker.php, which can now be
moved to an ImageBeforeProduceHTML hook subscriber. wikiHow uses those
changes together with the WikihowArticle extension to heavily modify the
article DOM for various extensions and the default skin.
