Currently unused_qualifications looks at the last segment of a path to see if it can be trimmed, this PR extends the check to the middle segments also

// currently linted
use std::env::args();
std::env::args(); // Removes `std::env::`
// newly linted
use std::env;
std::env::args(); // Removes `std::`

Paths with generics in them are now linted as long as the part being trimmed is before any generic args, e.g. it will now suggest trimming std::vec:: from std::vec::Vec<usize>

Paths with any segments that are from an expansion are no longer linted

Fixes #100979
Fixes #96698

Consider middle segments of paths in `unused_qualifications`

Currently `unused_qualifications` looks at the last segment of a path to see if it can be trimmed, this PR extends the check to the middle segments also

```rust
// currently linted
use std::env::args();
std::env::args(); // Removes `std::env::`
```
```rust
// newly linted
use std::env;
std::env::args(); // Removes `std::`
```

Paths with generics in them are now linted as long as the part being trimmed is before any generic args, e.g. it will now suggest trimming `std::vec::` from `std::vec::Vec<usize>`

Paths with any segments that are from an expansion are no longer linted
