fix(ivy): avoid missing imports for types that can be represented as values (#28941)

Prior to this change, TypeScript stripped out some imports in case we reference a type that can be represented as a value (for ex. classes). This fix ensures that we use correct symbol identifier, which makes TypeScript retain the necessary import statements. PR Close #28941
