OvmfPkg/MemEncryptSevLib: Check if SEV-SNP coherency mitigitation is needed
CPUID bit Fn8000001F_EBX[31] defines the COHERNECY_SFW_NO CPUID bit that,
when set, indicates that the software mitigation for this vulnerability is
not needed.
Add support to check for this CPUID bit and avoid the mitigation if set.
