The out-of-process font loader, now that it has moved to using
CTFontManagerCreateFontDescriptorFromData, does not need to create a
full CTFontRef anymore, but can instead wrap the out-of-process font
data into a CTFontDescriptorRef built from data. Doing that avoids
creating an extra CTFont copy in font_platform_data_mac, as we can merge
the data descriptor with the cascade list attributes, and only then
create the CTFontRef from it.
