Add pkcs11 engine support which allows using keys that are securely
stored on a HSM or TPM. To use this feature the user has to supply
an RFC 7512 compliant PKCS11 URI to a key instead of a file as an
argument to one of the key options. This change is fully backwards
compatible.
This change makes use of the openssl engine API which is deprecated
since openssl 3.0 and will most likely be removed in version 4. So
pkcs11 support will have to be updated to the openssl provider API
in the near future.

Neoverse V2: erratum 2719103
Cortex-A710: erratum 2701952

Cortex-A78: erratum 2712571
Cortex-A78AE: erratum 2712574

A new optional function pointer convert_pk is added to crypto_lib_desc_t.
A new function crypto_mod_convert_pk() will either call
