John Tytgat b00be9f609 [cff] Fix family name logic of pure CFF fontdata (#52056).
1. If `FamilyName' is present in the CFF font, use this for
   FT_Face's `family_name'.
2. Otherwise, use the face name and chop off any subset prefix.
3. If at this point FT_Face's `family_name' is set, use this
   together with the full name to determine the style.
4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
5. If we don't have a valid style, use "Regular".

Previously, FT_Face's `family_name' entry for pure CFF fontdata
nearly always was the fontname itself, instead of the `FamilyName'
entry in the CFF font (assuming there is one).

* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
