Removed TTF_PROP_FONT_FACE_POINTER

There's no guarantee that the version of FreeType linked with SDL_ttf is compatible with the version linked with the application. We'll have to explicitly add APIs for anything we expose from the font.

Maybe we should add TTF_FontInfo that takes a font file and face index as a parameter?
