Tobias Bosch 9c697030e6 feat(compiler): generate proper reexports in .ngfactory.ts files to not need transitive deps for compiling .ngfactory.ts files. (#13524)
Note: This checks the constructors of `@Injectable` classes more strictly.
E.g this will fail now as the constructor argument has no `@Inject` nor is
the type of the argument a DI token.

```
@Injectable()
class MyService {
  constructor(dep: string) {}
}
```
