The configuration variable "CategoryTreeForceHeaders" allowed to force
the loading of the modules on every page by the hooks
"BeforePageDisplay" and "BeforePageDisplayMobile".
This is not needed anymore because the modules are now already loaded
if the category tree is used some on the other hooks.

The CategoryTree::setHeaders() method adds modules to OutputPage.
It does not matter if setHeaders() gets called several times.
The previous code tried to avoid to call setHeaders() several times.
If wgCategoryTreeForceHeaders is set then the modules get loaded by the
hooks "BeforePageDisplay" or "BeforePageDisplayMobile" on every page.
In this case duplicate calls of setHeaders() are (partly) avoided by
not calling setHeaders() on other hooks.
This change removes this micro optimization and loads the modules
unconditionally if a category tree is added on a hook.
shouldForceHeaders() is now inlined.

The MediaWikiServices hook runs before the service container is fully initialized, so it cannot have services injected. For this reason, it needs to be separate from the handlers for other hooks.

This converts the CategtoryTree extension to the new (MW1.35) hook system.
The patch was written live during a hackathon workshop.

Re-applying after fixing: premature access to $wgRequest

NOTE: the "mode" parameter for category pages seems to be broken,
as the mode is not proeprly propoagated to dynamic requests.
This was already the case before this change, and this change
does not try to fix that issue. I was tempted to just remove
the feature entirely, but T137812 inidcates that it may be useful to
some. I will comment there to see if this should be fiexed or removed.
