Currently, the UEFI drivers using the SHA/SM3 hashing algorithms use hard-coded
API to calculate the hash, for instance, sha_256(...), etc. Since SHA384 and/or
SM3_256 are being increasingly adopted for robustness, it becomes cumbersome to
modify each driver that calls into hash calculating API.

To better achieve this, we are proposing a Unified API, which can be used by UEFI
drivers, that provides the drivers with flexibility to use the desired hashing
algorithm based on the required robnustness.

Alternatively, the design document is also attached to Bugzilla,
https://bugzilla.tianocore.org/show_bug.cgi?id=2151.
