g10: Remove deprecated internal functions.

* g10/keygen.c (do_ask_passphrase, generate_raw_key)
(gen_card_key_with_backup, save_unprotected_key_to_card): Remove.

--

Now, key generation is done by gpg-agent.  Asking passphrase is done
through pinentry invoked by gpg-agent.  It is done by
new internal function of card_store_key_with_backup.
