Add CryptoCB-based AES key import support to enable Secure Element
offload without exposing raw AES key material to wolfCrypt.
When WOLF_CRYPTO_CB_AES_SETKEY is defined, wolfCrypt invokes a CryptoCB
callback during AES key setup. Behavior is determined by the callback
return value:
- If callback returns 0: Key is imported to the device (aes->devCtx).
Key is NOT copied to wolfCrypt RAM; GCM H/M tables are NOT generated.
Full hardware offload is assumed.
- If callback returns CRYPTOCB_UNAVAILABLE: Device does not support
SetKey. Normal software path is used; key is copied to devKey for
optional encrypt/decrypt acceleration.
- Any other error: Propagated to the caller.
Key points:
- Add wc_CryptoCb_AesSetKey() callback for AES key import
- Update AES SetKey paths to call CryptoCB and branch on return value
- Skip GCM H/M table generation when callback succeeded (devCtx set)
- Preserve existing behavior when devId is INVALID_DEVID or
WOLF_CRYPTO_CB_AES_SETKEY is not defined
Testing:
- Add unit test for CryptoCB AES SetKey (verifies key isolation when
callback succeeds)
- Add end-to-end AES-GCM offload test (SetKey, Encrypt, Decrypt, Free
via CryptoCB)
- Tests use a mock SE with software AES to validate routing
Enable with: CPPFLAGS="-DWOLF_CRYPTO_CB_AES_SETKEY -DWOLF_CRYPTO_CB_FREE"

Mostly combinations of NO_WOLFSSL_CLIENT, NO_WOLFSSL_SERVER and
WOLFSSL_NO_CLIENT_AUTH were failing.
Added configurations to CI loop.
wc_AesGcmDecryptFinal: use WC_AES_BLOCK_SIZE to satisfy compiler.

tests/quic.c: wrap exercises in wolfSSL_Init()...wolfSSL_Cleanup();
tests/unit.c: in unit_test(), add several more fflush(stdout)s, report error from wolfSSL_Cleanup(), and fix line length;
wolfcrypt/test/test.c: omit reseed test in _rng_test() if HAVE_INTEL_RDRAND or old FIPS, and use simplified random_test() if HAVE_INTEL_RDRAND;
wolfssl/wolfcrypt/mem_track.h: add memList pointer in struct memoryStats, and set it in InitMemoryTracker();
wolfssl/wolfcrypt/settings.h: undefine WOLFSSL_SMALL_STACK_CACHE if WOLFSSL_SMALL_STACK is undefined;
