fix(intel): extending to support large file size for SHA-2 ECDSA data signing and signature verifying
This patch is to extend to support large file size
for SHA-2 ECDSA data signing and signature verifying.
The large file will be split into smaller chunk and
send using initialize, update and finalize staging method.
