Ensure vtable entries for generics are attached constants (#5853)
Otherwise these end up as unattached constants (see the baseline test changes) and can't be resolved by `GetConstantValueInSpecific` in lowering or in further derived vtables. If the class is non-generic, then it's fine for the vtable entry for some function inherited from a generic base is represented as an unattached constant, since the specific in that specific_function is already fully resolved. --------- Co-authored-by: Dana Jansens <danakj@orodu.net>
