std.crypto: add hybrid post-quantum/traditional key encapsulation

Hybrid KEMs combine a post-quantum secure KEM with a traditional
elliptic curve Diffie-Hellman key exchange.

The hybrid construction provides security against both classical and quantum
adversaries: even if one component is broken, the combined scheme remains
secure as long as the other component holds.

The implementation follows the IETF CFRG draft specification for concrete
hybrid KEMs:
