Add a method to retrieve RPATH/RUNPATH entries as a list of paths, enabling maturin to use arwen instead of goblin for reading rpath values. Related: PyO3/maturin#2932 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Use the arwen crate (a Rust port of patchelf) to read/modify ELF rpath, soname and DT_NEEDED entries instead of shelling out to patchelf. Removes the runtime dependency on the patchelf binary. The 'patchelf' optional extra in pyproject.toml is kept (empty) for backwards compatibility but is now deprecated.

Avoid the external patchelf library, use arwen instead.
This creates a split situation of using both goblin and arwen for binary parsing. It does less reparsing of ELF files than previously.
