\brief Enable ECC support for non-blocking operations. Supported for
Single Precision (SP) math with the following build options:
WOLFSSL_SP_NONBLOCK
WOLFSSL_SP_SMALL
WOLFSSL_SP_NO_MALLOC
WC_ECC_NONBLOCK
\return 0 Returned upon successfully setting the callback context the input message
\param key pointer to the ecc_key object
\param ctx pointer to ecc_nb_ctx_t structure with stack data cache for SP
_Example_
\code
int ret;
ecc_key ecc;
ecc_nb_ctx_t nb_ctx;
ret = wc_ecc_init(&ecc);
if (ret == 0) {
ret = wc_ecc_set_nonblock(&ecc, &nb_ctx);

ret = wc_ecc_verify_hash_ex(
&r, &s, // r/s as mp_int
hash, hashSz, // computed hash digest
&verify_res, // verification result 1=success
&key
);
// TODO: Real-time work can be called here
} while (ret == FP_WOULDBLOCK);
