Implement full client-server ML-KEM (Module-Lattice-Based Key Encapsulation Mechanism) support across all wolfHSM layers, enabling post-quantum key exchange operations to be offloaded to the HSM. Client API (wh_client_crypto): - Key management: import, export, set/get key ID - Key generation: MakeExportKey (ephemeral) and MakeCacheKey (server-cached) - Encapsulation and decapsulation operations - DMA variants for all operations Server handling (wh_server_crypto): - Request handlers for ML-KEM keygen, encapsulate, and decapsulate - Auto-import with evict-after-use for uncached keys - DMA request handlers Crypto callback integration (wh_client_cryptocb): - Register PQC KEM keygen/encaps/decaps handlers so wolfCrypt ML-KEM calls are transparently forwarded to the HSM via WH_DEV_ID Message layer (wh_message_crypto): - Define request/response structures for keygen, encapsulate, decapsulate - Endian translation functions for cross-platform support Shared utilities (wh_crypto): - ML-KEM key serialization/deserialization with automatic level probing Supports all three ML-KEM parameter sets (512, 768, 1024). Includes tests for all operations and DMA paths, and benchmarks for keygen, encaps, and decaps at each security level. Also fixes key export response to use actual stored key length from NVM metadata instead of the request size.
