fix(nu-command): support ACL, SELinux, e.g. in cd have_permission check (#15360)
fixes #8095


# Description


This approach is a bit straightforward, call access() check with the
flag `X_OK`.

Zsh[^1], Fish perform this check by the same approach.

It could also avoid manual xattrs check on other *nix platforms.

BTW, the execution bit for directories in *nix world means permission to
access it's content,
while the read bit means to list it's content. [^0]

# User-Facing Changes

Users could face less permission check bugs in their `cd` usage.

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.

Collection of small utilities that are shared across Nushell crates.

This crate should compile early in the crate graph and thus not depend on major dependencies or core-nushell crates itself.

Internal Nushell crate

This crate implements components of Nushell and is not designed to support plugin authors or other users directly.
