mediawiki.special: Combine various tiny specialpage style modules

These stylesheets are sufficiently tiny that it doesn't make sense to
offer them the ability to be loaded separately from each other (saving
bytes in double-digits) at the cost of 1) exporting a dedicated registry
item with meta data shipped on every page view, 2) reduced cache re-use
from increased fragmentation.

Instead, move these to the 'mediawiki.special' style module.
The entries retain their own files to keep them as easy to find
and edit as before.

Where not already, ensure addModuleStyles() is always placed above
any addModules() call in the same method. The load order isn't
affected by the call order, but given blocking style-modules load
before async JS, it helps to order them in a way that visually
matches the effective load order (from top to bottom).

The following 7 modules were remove without deprecation:

1. "mediawiki.special.apisandbox.styles" (1 rule)
2. "mediawiki.special.edittags.styles" (3 rules)
3. "mediawiki.special.movePage.styles" (1 rule)
4. "mediawiki.special.pagesWithProp" (1 rule)
5. "mediawiki.special.upload.styles" (2 rules)
6. "mediawiki.special.watchlist.styles" (3 rules)
7. "mediawiki.special.comparepages.styles" (4 rules)

These module names were only used on the core classes loading them, and
aren't depended on outside core by module name, rather, extensions and
gadgets depend on the styles styles being loaded in a blocking manner on
these pages, which remains unaffected.
