SecurityPkg: introduce the SM3 digest algorithm
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1781
GITHUB: https://github.com/idesai/edk2/tree/enable_sm3_measured_boot_v6
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 add SM3 algorithm in the hashinstance library.
Delta in v7:
1. Dropped 95a040cff from v6 to address https://edk2.groups.io/g/devel/topic/
32454898?p=,,,20,0,0,0::Created,,sm3,20,2,0,32454898,ct=1&ct=1
2. Relocated SM3 GUID definition from MdePkg to SecurityPkg in 9728b54f4
