Implement SUCI Profile Scheme A for 5G UE

Browse Source 
Extend UICC configuration parsing to provide: routing_indicator,
protection_scheme, home_network_public_key, and home_network_public_key_id.
Use the protection_scheme value to decide what SUCI Profile Scheme to
apply during SUCI generation. Add support for Profile Scheme A which
provides ECIES-based encryption using Curve25519 and X9.63 KDF as outlined
in TS 33.501 Section C.3.4.1 Profile A.

When a configuration file specifies an unsupported Profile Scheme,
the NAS layer triggers a fatal error. This occurs either because
Profile Scheme B is unimplemented or the build uses OpenSSL < 3.0,
which lacks Curve25519 and X9.63 KDF support, ensuring users are
informed of the incompatibility.
