    PangoWin32: Make PangoWin32Font type checks public
    
    This can be useful so that we can check against which backend is being
    used on Windows, as it can be either Win32 or FontConfig/FreeType.
    
    Also rename cases of PANGO_WIN32_IS_FONT to PANGO_IS_WIN32_FONT, to fit
    what is more commonly used--as PANGO_WIN32_IS_FONT was private, we can
    get away with that without breaking ABI/API.
