[clang] Fix isInStdNamespace for Decl flagged extern c++ (#81776)
The MSVC STL implementation declares multiple classes using:
```cpp
namespace std {
extern "C++" class locale {
...
};
}
```
`isInStdNamespace` uses the first DeclContext to check whether a Decl is
inside the `std` namespace. Here, the first DeclContext of the `locale`
Decl is a LinkageSpecDecl so the method will return false.
We need to skip this LinkageSpecDecl to find the first DeclContext of
type Namespace and actually check whether we're in the `std` namespace.
