Subject: Revert "SecurityPkg: set SM3 bit in TPM 2.0 hash mask by default"

This reverts commit d5af8fc5a975feb6c745587d0d834733ad2048fd.

The reason is that said commit indirectly depends on commit 49c1e683c452
("MdePkg/Protocol/Hash: introduce GUID for SM3", 2019-07-03), and the
latter commit is going to be reverted, due to its review process not
having followed established edk2 norms.
