[WIP] resourceloader: Merge 'user.groups' into 'user' module

This is with T92459 in mind to simplify the process of splitting
the 'user' module for the styles-only queue.

Consequences:

* Cached HTML isn't relevant in practice since there is no caching for logged-in
  users and this module is only for logged-in users. Even then, cached HTML will
  work and may happen as browsers re-use HTML responses when revisiting a
  privately cached page (after 304 Not Modified).
  Note that OutputPage (via isKnownEmpty) only actually tries to load 
'user.groups'
  if the wiki has 'MediaWiki:Group-*.{js,css}' pages for the current user's 
groups.

  - Old style queue request will continue to ask for user.groups which is now a
    FileModule with no styles (simply concats the empty string to the bundle)
  - Old load() request will resolve with an empty function.

* The are no known dependants of 'user.groups'. If there are, they will work
  by proxy of it now being an empty module that just ensures 'user' is loaded.

* The security origin of 'user.groups' was USER_SITEWIDE. The origin of 'user'
  is lower (USER_INDIVIDUAL). Pages that are restricted to USER_SITEWIDE
  previously received user.groups, but won't anymore. This should be fine as
  OutputPage::reduceAllowedModules() is mainly used to either allow everything
  or restrict all the way down to CORE. The only exception is disallowUserJs()
  if $wgAllowSiteCSSOnRestrictedPages is enabled (T73621) but that edge case was
  made for Common.css, not Group-*.css.
