Windows native font engine supports scaling of non-scalalble fonts, so
make it possible to do so.
Added two functions to QPlatformFontDatabase: fontsAlwaysScalable() and
standardSizes(), and made fontsAlwaysScalable() to return true for
Windows native font database.
Windows Freetype font engine doesn't seem to support scaling of
non-scalable fonts, so didn't enable it in there.
Added implementation of standardSizes() for Mac OS.
