Completely remove Chebychev remains from codebase

c6ab83f5742bc5ac6f9cb9a8b2a4f1ea241b6f63 already removed their availability
in user facing application, but the library code remained, and appeared to be
unused by the rest of the library, and not available to library users,
the API being only in proj_internal.h. So remove all remains.
