CryptoPkg: Add xxxxHashAll APIs to facilitate the digest computation

Browse Source 
Add new xxxxHashAll APIs to facilitate the digest computation of blob
data. New APIs include: Md4HashAll(), Md5HashAll(), Sha1HashAll(),
Sha256HashAll(), Sha384HashAll(), and Sha512HashAll().

The corresponding test cases were added in Cryptest utility.
