RFR: 8352970: Remove unnecessary Windows version check in Win32ShellFolderManager2 [v2]

[Daniel Gredler]

> Win32ShellFolderManager2 contains a check as to whether the current Windows version is Windows 2000 or later. The current minimum supported version is Windows 10, so this is no longer needed.
> 
> No test seems to currently exercise this code, and it's not easy to reliably test, but I've added a basic test that should surface any fundamental issues. The change is very simple, though.
