refactor(core): add single type for injector token (#41580) 

Currently we have a lot of places where we repeat the type `Type<T>|AbstractType<T>|InjectionToken<T>` which makes it cumbersome to add another type or to type something else with the same signature.

These changes add a new type that can be used instead.

Fixes #39792.

PR Close #41580
