We need to load these only when VisualEditor is loaded. This is
the best way to ensure that. They have been haphazardly placed
in different files.
The goal of this change is to move content styling for Minerva out of
mobile.editor.ve/minerva.less, and thus to be able to move this file
to mediawiki/extensions/MobileFrontend (T202978). But I spotted the
other places while working on that.
Moved as-is:
* skins.minerva.content.styles/links.less
* mobile.editor.ve/minerva.less
No longer needed:
* skins.minerva.content.styles/text.less
Parsoid now uses <sup> tags for references rather than <span>,
so the existing rules for <sup> tags are enough. See T45094,
<https://www.mediawiki.org/wiki/Specs/HTML/1.6.0/Extensions/Cite>.
Was never needed:
* skins.minerva.content.styles/thumbnails.less
The styles from the core module 'mediawiki.skinning.content.parsoid'
are never loaded, so we don't need to override them.
