tdf#103725: Fix horizontal scaling on Windows
* Restore the hack for adjusting font width on Windows, for the life of
me I canât find where we change font width or why I get different
values on Windows than Linux.
* Create IDWriteFont from LOGFONT instead of HDC, as it seems the later
will discard the font width.
