More mionr optimizations (#553)

* Optimize `BinFile::preview_bin`: Use `Path::display` instead of `to_string_lossy` to avoid allocation.
* Refactor: Rm useless `AsRef::as_ref` call
* Optimize `GhCrateMeta::find`: Reduce fut size by converting `Url` to `String`
   `Url` is much larger than `String`.
* Refactor `PackageInfo::resolve`: Destruct `Meta::binstall`
* Optimize `resolve::load_manifest_path`: Avoid allocation
