fix(ivy): set proper implementation for module injector (#28667)

Browse Source 
Prior to this change we used current injector implementation for module injector, which was causing problems and produces circular dependencies in case the same token is referenced (with @SkipSelf flag) in the `deps` array. The origin of the problem was that once `directiveInject` implementation becomes active, it was used for module injector as well, thus searching deps in Component/Directive DI scope. This fix sets `injectInjectorOnly` implementation for module injector to resolve the problem.
