wolfcrypt/src/aes.c, wolfcrypt/src/cmac.c, wolfssl/wolfcrypt/aes.h, wolfssl/wolfcrypt/types.h: optimizations to mitigate performance regressions from 299e7bd (#9783):

* add prefetch_ptr flag argument to AesEncrypt_C() and AesDecrypt_C(), and call PreFetchTe() and PreFetchSBox() only if *prefetch_ptr is zero, whereupon it is set to 1;
* when C implementations are available, add prefetch_ptr arg to wc_AesEncrypt() and wc_AesDecrypt(), and pass it through;
* in functions that directly call the AES block encryption methods, opportunistically inhibit prefetch on all but the first call;
* move AES-specific code in wc_CmacUpdate() in cmac.c to wc_local_CmacUpdateAes() in aes.c to let it use conditional prefetching;
* add WC_ARG_NOT_NULL(), WC_ARGS_NOT_NULL(), and WC_ALL_ARGS_NOT_NULL attribute abstractions.
