I think this is just a dead code so a followup PR could get rid of all CUSTOM_MINGW occurrences.

pacboy -S --noconfirm toolchain:p
# According to the comment in the Windows part of install-clang.sh, in the future we might
# want to do this instead:
# pacboy -S --noconfirm clang:p ...
pacman -S --noconfirm --needed mingw-w64-$arch-toolchain

I don't see MSYS2 anywhere in this script apart from the comment and filename, probably could be renamed to setup-windows-python.sh or something like that.

Yeah, I'm not convinced this script is still needed at all but I didn't want to change too much at once. Or if it is just needed by the mingw targets then it could be merged into the other script.

I think all Windows jobs need Python setup one way or another and after these changes this script is basically a custom actions/setup-python step: https://docs.github.com/en/actions/automating-builds-and-tests/building-and-testing-python#specifying-a-python-version

Hm, that says "To maintain consistent behavior with other runners and to allow Python to be used out-of-the-box without the setup-python action, GitHub adds a few versions from the tools cache to PATH"

Consistent behaviour with other runners sounds like something we can rely on, no?

We use custom Docker images on Linux builders, no idea about Mac. So this consistency won't really apply here.

Ah, I see. I think I'll experiment with maybe using the action in a follow up PR.
