[temp accounts] Make use of isKnown config flag

Why:

- A few places in core should check the isKnown
  flag (I4ce534a847461230f7fa276a565bdc1d6c9857e1) rather than isEnabled

What:

- Update ChangesListSpecialPage, UserGroupManager,
  UserSelectQueryBuilder, WatchedItemQueryService,
  ApiQuerySiteInfo, maintenance/expireTemporaryAccounts and
  maintenance/userOptions to used the isKnown() config check

Bug: T356524
