[Clang][Sema] Require BaseClass:: (not other classes) in member using-declaration in C++98 mode (#143492) ...

[CWG400](https://wg21.link/cwg400) rejects member using-declaration
whose nested-name-specifier doesn't refer to a base class of the current
class.

```cpp
struct A {};
struct B {
  using B::A; // error
};
```

Clang didn't reject this case in C++98 mode. This patch fixes this
issue.
