Subject: [PATCH 01/34] EP11: Unify key-pair generation functions

Unify the DSA and DH key-pair generation functions with those for
RSA, EC and Dilithium. Make sure that the attribute handling is done
in the same sequence for all those functions.

Also remove obsolete parameters for all the key-pair generation functions.
