OvmfPkg: Add support to perform SEV-ES initialization

Browse Source 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198

When SEV-ES is enabled, then SEV is also enabled. Add support to the SEV
initialization function to also check for SEV-ES being enabled, and if
enabled, set the SEV-ES enabled PCD (PcdSevEsIsEnabled).
