[WIN32SS][NTGDI] Registry-based font management (#1816)
CORE-16269
- Add IntGdiAddFontResourceEx function that is extended from IntGdiAddFontResource, in
order to add dwFlags parameter.
- Add IntLoadFontsInRegistry function that will load the fonts from registry info.
- If loading from registry failed, IntLoadSystemFonts will be called.
- Use IntLoadFontsInRegistry rather than IntLoadSystemFonts in the OS startup.
- Add NameFromCharSet function.
- Append " (CharSetName)" to registry value name if not TrueType.
