CryptoPkg/BaseHashApiLib: Align BaseHashApiLib with TPM 2.0 Implementation 

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.
