Imran Desai 542d04e2a4 SecurityPkg/HashLibBaseCryptoRouter: recognize the SM3 digest algorithm
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1781

EDK2 Support for SM3 digest algorithm is needed to enable TPM with SM3 PCR
banks. This digest algorithm is part of the China Crypto algorithm suite.
This integration has dependency on the openssl_1_1_1b integration into
edk2.
This patch adds SM3 as an available digest algorithm to crypto router.
