For example :

extern "C" {
    #[used] //~ ERROR attribute must be applied to a `static` variable
    static FOO: i32; // show the kind of this item to help user understand why the error is reported.
}

fixes #126789

Show `used attribute`'s kind for user when find it isn't applied to a `static` variable.

For example :
```rust
extern "C" {
    #[used] //~ ERROR attribute must be applied to a `static` variable
    static FOO: i32; // show the kind of this item to help user understand why the error is reported.
}
```
