Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=2511
This commit aligns the baseHashApiLib with TPM 2.0 Implementation
as follows:
- Remove reference to MD4 and MD5 algorithms as they are deprecated
- Align the enumerations for hashing algoerithms with the one used
in TPM 2.0 implementation defined in IndustryStandard/Tpm20.h.
