[!!!][TASK] Remove usage of ReflectionService in ViewHelpers
The ``AbstractViewHelper`` now uses compile static to get all
needed information about the render method of ViewHelper implementations.
As the AbstractViewHelper doesn't use the ReflectionService
anymore it was removed. This is breaking if a ViewHelper implementation
relies on the fact that ``$this->reflectionService`` is available. A
code migration warns about the possible usage of it.
Releases: master, 2.3
