trim() would always return a string, even with null as input
Keep the strval to make visible that this gets unsafe input

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.

This allows better to style the buttons.
The complicated CSS selector for the direction supports a categorytree
in the user interface language like in the sidebar or on
Special:CategoryTree and in the content language like on category pages
and with <categorytree> in the content.
The CSS selector :dir( rtl ) would be a short version for this but it is
currently only supported by Firefox:

A categorytree can be part of the user interface (in the sidebar) or
part of the content. The user interface and the content can have a
different text direction.
This change use the usual way to of bidi flipping based on the user
interface language direction and on the content direction like the class
mw-editsection in core.
The direction of the bullets in mixed directions will be fixed in
Ibfb0cb28f0086fb1b7d0997be2246bc120eea85e.

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.
