Subject: [PATCH] By tracking import use types to check whether it is scope
 uses or the other situations like module-relative uses, we can do more
 accurate redundant import checking.

fixes #117448

For example unnecessary imports in std::prelude that can be eliminated:

```rust
use std::option::Option::Some;//~ WARNING the item `Some` is imported redundantly
use std::option::Option::None; //~ WARNING the item `None` is imported redundantly
```
