tests/qtest: Add test for Aspeed HACE accumulative mode 

This add two addition test cases for accumulative mode under sg enabled.

The input vector was manually craft with "abc" + bit 1 + padding zeros + L.
The padding length depends on algorithm, i.e. SHA512 (1024 bit),
SHA256 (512 bit).

The result was calculated by command line sha512sum/sha256sum utilities
without padding, i.e. only "abc" ascii text.
