Dedupe Unix & WASI stdlib - #8635

📝 WalkthroughWalkthroughThe change adds a shared ChangesPOSIX-like module integration
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The refactor centralizes Unix/WASI stdlib behavior, but non-WASI compatibility builds currently fail because remove lacks the required filesystem import; merge should wait for that localized fix.

Follow up to RustPython#8591 because I figured out how to deduplicate the code. This is nicer for future patches that improve WASI support because Unix-likes and WASI can often share the same dispatch functions.

Remove the unused TargetIsDirectory import.
The module no longer references TargetIsDirectory. This import produces an unused_imports warning.
As per coding guidelines, **/*.rs: Always run cargo clippy and fix warnings or lints introduced by Rust changes.
