[FE 1.0] Don't use BuilderInferenceSubstitutionConstraintPosition for declared upper bound constraint with no substituted upper bound
It leads to further infer type variable into those upper bounds which is forbidden Substituted upper bounds is ok because specific substituted types came from constraints of other proper positions, or if specific substituted type is from declared upper bound too, then there should be another declared upper bound with no substitution ^KT-51464 Fixed ^KT-47986 Fixed
