Qin Long 2ac68e8b54 CryptoPkg Updates to support RFC3161 timestamp signature verification.
The main changes includes:
1. Enabling SHA384 and SHA512 digest algorithm; (Sha512.c)
2. RFC 3161 timestamp signature verification support; (CryptTs.c)
3. Fixed one ASN.1 length encoding issue in Authenticode verification routine. (CryptAuthenticode.c)
4. Add the corresponding test cases in Cryptest utility (SHA384 & SHA512 & Timestamp verification)
