Brijesh Singh f1d1c337e7 OvmfPkg/BaseMemEncryptLib: use the SEV_STATUS MSR value from workarea ...

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3582

Improve the MemEncryptSev{Es,Snp}IsEnabled() to use the SEV_STATUS MSR
value saved in the workarea. Since workarea is valid until the PEI phase,
so, for the Dxe phase use the PcdConfidentialComputingGuestAttr to
determine which SEV technology is enabled.
