  [Clang] Remove `IDNS_Ordinary` flag in `IndirectFieldDecl::IdentifierNamespace` (#100525)

There is a `IDNS_Ordinary` flag in
`IndirectFieldDecl::IdentifierNamespace` so that members in nested
anonymous struct/union can be found as ordinary identifiers.

```c
struct S {
  struct { int x; };
  // Previous behaviour: `x` in previous line is found
  // Expected: nothing is found
  int arr[sizeof(x)];
};
```

This PR fixes this issue.

Fixes #31295.
