[cff] Remove `FT_CONFIG_OPTION_NO_GLYPH_NAMES`.

This ancient option stayed completely undocumented.  Given that the 'cff'
driver requires the 'psnames' module, it makes no sense today to have this
macro.

* src/cff/cffdrivr.c (cff_services), src/cff/cffobjs.c (cff_face_init):
Remove corresponding conditional code.
