gpg: Add a notation to Kyber encryption subkeys

* g10/keygen.c (struct opaque_data_usage_and_pk): New.
(do_add_notation): New.
(keygen_add_key_flags_from_oduap): New.
(write_keybinding): Prepare for de-vs cplimance notation.  Add a
notation to Kyber subkeys.

This code is based on the 2.2
commit b284412786d71c1cf382e1dff3a36ec6cce11556
However the de-vs notation is currently ineffective as long as
Libgcrypt won't claim compliance.

The new notation fips203.ipd.2023-08-24 has been added to allow
detection of subkeys which have been crated with a pre-final FIPS203
spec for Kyber.
