Auto merge of #30294 - jseyfried:fix_shadowed_use_visibility, r=nrc

This fixes a bug in which the visibility of a use declaration defining a name in one namespace (e.g. the value namespace) is overridden by a later use declaration defining the same name in the other namespace (e.g. the type namespace). For example,
```rust
fn f() {}
pub mod bar {}

mod foo {
    use f; // This import should not be visible outside `foo`,
    pub use bar as f; // but it visible outside of `foo` because of this import.
}

fn main() { foo::f(); }
```
As the example demonstrates, this is a [breaking-change], but it looks unlikely to cause breakage in practice, and any breakage can be fixed by correcting visibility modifiers.
