Rollup merge of #88953 - joshtriplett:chown, r=dtolnay

Add chown functions to std::os::unix::fs to change the owner and group of files

This is a straightforward wrapper that uses the existing helpers for C
string handling and errno handling.

Having this available is convenient for UNIX utility programs written in
Rust, and avoids having to call unsafe functions like `libc::chown`
directly and handle errors manually, in a program that may otherwise be
entirely safe code.

In addition, these functions provide a more Rustic interface by
accepting appropriate traits and using `None` rather than `-1`.
