refactor(driver): Refactored directory link check logic (#9324)

- Use `filePath` variable to simplify path handling
- Replace `isSymlinkDir` with `isLinkedDir` in `isFolder` check
- Use simplified path variables in `times.Stat` function calls

refactor(util): Optimized directory link check functions

- Renamed `isSymlinkDir` to `isLinkedDir` to expand Windows platform support
- Corrected path resolution logic to ensure link paths are absolute
- Added error handling to prevent path resolution failures
