gpg: New option --disable-pqc-encryption.

Browse source 
* g10/options.h (flags): Add field disable_pqc_encryption.
* g10/gpg.c (oDisablePQCEncryption): New.
(opts): Add --option.
(main): Set option.
* g10/getkey.c (finish_lookup): Skip subkeys if option is set.
--

This option can be used to avoid the use of Kyber encryption subkeys
if this does not make sense (i.e. protection of local files).
