windows: add IsWow64Process2 for detecting x86 on arm

The original IsWow64Process returns false on arm, always, and so
IsWow64Process2 was added to account for this scenario. This isn't
available on older versions of Windows, so we mark it as such using the
new '?' notation. Finally, we add a test to make sure this all works and
does the expected thing on different versions of Windows.
