This call *attempted* to avoid setting the `INIT_FACTORY` on items which did not need it (specifically, it avoided setting it on things which were not instantiable), but ultimately failed to do. It was ultimately setting the new `FactoryManager` instance as the `INIT_FACTORY` value on each instantiable object, which includes classes and not just class instances, since objects are only treated as non-instantiable when they explicitly specify `instantiate: false`. The net was a memory leak: the routing service *class* ended up with an `INIT_FACTORY` pointing to a `FactoryManager` instance which in turn always had a `container` on it, which meant that there was a cycle (the container also referenced the service) and thus a leak. This affects both tests and FastBoot, where we construct new instances of the service whenever we call the `visit` API.
Identified as part of the work on #20025, this particular `setFactoryFor` was needed at one time but is now defunct. Remove it.
