[New-bugs-announce] [issue41627] Relocate user site packages on Windows 32-bit

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

Currently, the user site packages on Windows is %APPDATA%\Python\PythonXY. This can cause conflicts between the 32-bit and 64-bit versions of the runtime.

We should switch the pattern to Python{sys.winver}, which is XY or XY-32, the same as elsewhere.

This is a breaking change to tools that try to manage these directly, but it shouldn't need a deprecation cycle (there isn't really anywhere to raise a warning...). So I think we can just update Lib/sysconfig.py and Lib/site.py for 3.10, as well as the docs.
