In #34021 the ngtsc compiler gained the ability to emit type parameter constraints, which would generate imports for any type reference that is used within the constraint. However, the `AbsoluteModuleStrategy` reference emitter strategy did not consider interface declarations as a valid declaration it can generate an import for, throwing an error instead. This commit fixes the issue by including interface declarations in the logic that determines whether something is a declaration. Fixes #34837 PR Close #34849
