Blind attempt to fix UBSAN error in FreetypeFont

The only place that calls FreetypeFontInstance::SetFreetypeFont() is
FreetypeFont::FreetypeFont() calling it with “this”:

    static_cast<FreetypeFontInstance*>(mpFontInstance)->SetFreetypeFont( this );

So I don’t think we need to manage that FreetypeFont pointer, as it it
is guaranteed to be valid as long as this FreetypeFontInstance is valid.

Too many font classes and it is really hard to reason what is doing
what…
