[New-bugs-announce] [issue45720] Remove shlwapi dependency on Windows

[Steve Dower]

New submission from Steve Dower <steve.dower at python.org>:

According to https://twitter.com/BruceDawson0xB/status/1455714820485894151?s=20 there are some serious performance implications from referencing shlwapi.dll.

It turns out, we only use it for one native path calculation function, which is easily replaceable (since Windows 8). So we can drop the dependency and get a startup (and shutdown) improvement back to 3.9.
