feat: Add macOS Alias Support

[Equationzhao]

Currently, eza cannot display the target path of macOS alias files.

Unlike symlinks, alias maintains dynamic reference via file ID tracking, working even when target files move.

Expected Behavior

Similar to how eza handles symlinks:

$ eza -l
.rw-r--r--@  800 username time alias_file -> /path/to/target

This sound like we would need to call specific macOS APIs, not sure if there’s something in Rust to do that:
