Add LMS and XMSS PQC benchmark modules#454

Add KeyGen/Sign/Verify benchmarks for the two stateful hash-based PQC
schemes wolfHSM supports: LMS (L1/H5/W8) and XMSS (SHA2_10_256). Both
are DMA-only, so each operation is a single variant.
Verify runs against embedded precomputed (public key, signature)
vectors instead of generating them at runtime, so it is available in
verify-only builds (guarded by WOLFSSL_HAVE_{LMS,XMSS}); keygen and
sign require a signing build (!WOLFSSL_{LMS,XMSS}_VERIFY_ONLY).
The stateful sign benchmark clamps its iteration count to the key's
2^H one-time-signature budget (logging when it caps) so raising the
shared WOLFHSM_CFG_BENCH_PK_ITERS does not exhaust the key. Each
generated key is erased from server NVM after the measured operation.
Enable LMS/XMSS in the benchmark config and raise MAX_BENCH_OPS to fit
the new modules.
