CryptoPkg/BaseHashApiLib: Implement Unified Hash Calculation API

https://bugzilla.tianocore.org/show_bug.cgi?id=2151

This commit introduces a Unified Hash API to calculate hash using a
hashing algorithm specified by the PCD, PcdHashApiLibPolicy. This library
interfaces with the various hashing API, such as, MD4, MD5, SHA1, SHA256,
SHA512 and SM3_256 implemented in BaseCryptLib. The user can calculate
the desired hash by setting PcdHashApiLibPolicy to appropriate value.

This feature is documented in the Bugzilla,
https://bugzilla.tianocore.org/show_bug.cgi?id=2151.
