Merge OBJ_NAME_do_all*(3) into EVP_CIPHER_do_all(3)

This is the only OBJ_NAME API that will remain after the next major bump.
The API is misnamed and really is about EVP, so move it to an EVP manual
documenting another API doing essentially the same thing. Remove most cross
references to OBJ_NAME_*.
