Error out when someone tries to use msys/python to run Meson
This mistake seems to be a very common hiccup for people trying to use
Meson with MSYS2 on Windows from git or with pip.
msys/python uses POSIX paths with '/' as the root instead of a drive
like `C:/`, and also does not identify the platform as Windows.
This means that configure checks will be wrong, and many build tools
will be unable to parse the paths that are returned by functions in
Python such as shutil.which.
Closes https://github.com/mesonbuild/meson/issues/3653
