Finish the ObjectManager usages in ext:fluid. With #94285
we made the ViewHelperResolver a singleton service, which
is not ok since it holds state: Namespaces are added at
runtime and they additionally depend on request.
The solution is similar to RenderingContext from #94285
though: Have a factory to create fresh instances for
each parsing cycle for this failsafe mode enabled class.
View helper instance prototypes itself are then retrieved
using GeneralUtility::makeInstance().
