Auto merge of #84522 - CDirkx:cmath, r=yaahc

Reuse `sys::unix::cmath` on other platforms

Reuse `sys::unix::cmath` on all non-`windows` platforms.

`unix` is chosen as the canonical location instead of `unsupported` or `common` because `unsupported` doesn't make sense semantically and `common` is reserved for code that is supported on all platforms. Also `unix` is already the home of some non-`windows` code that is technically not exclusive to `unix` like `unix::path`.
