Add back description links when !$wgParserEnableLegacyMediaDOM

Browse source 
The approach taken here is the same as in core for magnify links on
thumbs in Id46d1b2ab1af3baebff13e10f1485f3cfd9a4b37

The gist is that resource attributes are added on the mw-file-element so
that the necessary url is present in the html.  A class is also added to
the wrapper element that designates where the link should be positioned.
Finally, a script adds the link which styles in appropriately.

Bug: T329364
