Rollup merge of rust-lang#138949 - madsmtm:rename-to-darwin, r=WaffleLapkin

Rename `is_like_osx` to `is_like_darwin`

Replace `is_like_osx` with `is_like_darwin`, which more closely describes reality (OS X is the pre-2016 name for macOS, and is by now quite outdated; Darwin is the overall name for the OS underlying Apple's macOS, iOS, etc.).
