gpg: Support dual keygrips.

Browse source 
* g10/keyid.c (keygrip_from_pk): Add arg get_second to support dual
algos.  Implement for Kyber.
(hexkeygrip_from_pk): Extend for dual algos.
* g10/call-agent.c (agent_keytotpm): Bail out for dual algos.
(agent_keytocard): Ditto.
(agent_probe_secret_key): Handle dual algos.
(agent_probe_any_secret_key): Ditto.
(agent_get_keyinfo): Allow for dual algos but take only the first key.
* g10/export.c (do_export_one_keyblock): Bail out for dual algos.

This also adds some fixmes which we eventually need to address.
