[freetype2] master 0b429b6: [builds/windows] Try both wide and narrow `CreateFile`

    [builds/windows] Try both wide and narrow `CreateFile`
    
    Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
    filenames using alternative -A and -W API. We'll try them both
    when opening a file. This means that you should not worry about
    about conversions.
    
    Fixes #1098 and !76.
    
    * builds/windows/ftsystem.c (FT_Stream_Open): Call alternative
    `CreateFile` in the case of failure.
