Base.subproject: correct home directory handling on Windows

While we can enumerate the users using `NetUserEnum`, that does not
guarantee that we get the full user information.  Perform an explicit
`NetUserGetInfo` to query the user information to get the home
directory.

Additionally, correct the `CFString` handling within the function where
we were improperly using `CFStringCreateWithBytesNoCopy` which requires
that the string is 8-bit encoded.  We now use
`CFStringCreateWithCharacters[NoCopy]` to properly create the `CFString`
with unicode characters.
