[issue44579] shutil.copy() inefficient implementation in Windows

This is true today, but could change whenever Windows feels like changing it. If we switch to the native API then we'll get any advantage there automatically.

The only challenge is in managing changes to semantics (that is, anything extra we do to "match" Unix that isn't normally how copies work on Windows - personally, I'd rather be more native on Windows anyway).
