Remove win32-dir code / references from Facter

win32-dir uses the Shell APIs to find common directories on Windows. Find an alternative solution that doesn't require CSIDL

The Puppet solution is a bit more complicated as it will need to produce the same api where Dir is adorned with new constants.

Facter only uses COMMON_APPDATA and only in one spot.

See https://gist.github.com/Iristyle/057c5560dbe64532fd1770a36e51f805 for more details on why this is important.

A follow up to this should remove the actual gem from vendored Ruby.
