fix(ivy): provided Injector should be instantiated by its factory (#27456)

Browse Source 
(FW-777)

When an Injector is provided, R3Injector instantiates it by calling its
constructor instead of its factory, not resolving dependencies.
With this fix, the ngInjectorDef is checked and the factory is correctly
used if it is found.
