Rollup merge of #134420 - Integral-Tech:pathbuf-refactor, r=compiler-errors

refactor: replace &PathBuf with &Path to enhance generality

- According to [style.md](https://github.com/rust-lang/rust/blob/master/src/tools/rust-analyzer/docs/dev/style.md#useless-types):

> More generally, always prefer types on the left
```rust
// GOOD      BAD
&[T]         &Vec<T>
&str         &String
Option<&T>   &Option<T>
&Path        &PathBuf
```
