FreeType: Support RGB rendering when not using FontConfig
Windows+FreeType, Linux with -no-fontconfig and the forthcoming OSX FreeType engine can now use sub pixel rendering. The function to get the subpixel type is in QPlatformScreen because we're moving to per screen font settings in the future. This patch is safe, as no functionality is changed for existing users, if one wants sub pixel rendering they'll still have to pass -DFT_CONFIG_OPTION_SUBPIXEL_RENDERING to configure.
