RFC: Drop native Windows support for WSL2

[pombredanne]

There are many problems derived from supporting native Windows: since we are dealing with a lot of lower level paths and files and bytes handling we are exposed to many of the subtle differences between POSIX and Windows. As a result there is a lot of code that just handles all these quirks.
With the advent of a decent POSIX support in Windows 10, I would like to drop entirely native Windows support and only support WSL. This basically means that we support Linux on Windows. This would simplify the codebase vastly, as well as the CI and tests.

This means that WSL https://docs.microsoft.com/en-us/windows/wsl/install-win10 would become a requirement on Windows.

I've used pip with Bash on Windows (in Windows Terminal) with good success. Will that continue to be an option / recommendation?

Is this using cygwin? git bash? WSL2? which version of Python?

[BigBlueHat]

git bash with Python 3.7.4. However, now that I'm trying to upgrade to the last version I am running into snags...but I've not yet determined if that's on my side (probably) or something wrong with scancode-toolkit specifically (probably not).

When I started to upgrade I tried the native Windows install (to replace my old pip-based install), but that sent me here...so now I'm back to pip...until I (probably) give up and try WSL--which I generally try to avoid due to the added layer of abstraction/tools/etc.

The latest ScanCode v21.8.4 has been released today to fix this issue. Do you mind to try it out?

@pombredanne ：

The problem was successfully resolved. After testing, the scancode -h command can be executed correctly in windows
