code/windows.c: add method for converting from utf16 to utf8

Modify the funcion system_default_path_append() to
both receive and return wchar_t types.

Remove fallback in system_default_path_append()
as this is now redundant.

Add a function utf16_to_utf8() and use that
in places where system_default_path_append() needs
to be converted to utf8.

Move both utf16_to_utf8*() and utf8_to_utf16*()
near the top of the file.
