  [Cocoa] Defer creating CTFonts a little longer for "special case" fonts

Reviewed by Cameron McCormack.

https://bugs.webkit.org/show_bug.cgi?id=247987 is about how we need to defer the
CTFontDescriptor -> CTFont transformation until as late as possible, to avoid
ping-pinging between fonts and descriptors. This pach takes one small step toward
that goal, by preserving the CTFontDescriptor slightly longer when we create
a CTFont for our so-called "special case" fonts.
