OvmfPkg/AmdSev: reserve snp pages
The SNP patch series updated the OvmfPkgX64 build but forgot the AmdSev
variant, resulting in a broken OvmfSevMetadata table.
Fixes: cca9cd3dd6bf ("OvmfPkg: reserve CPUID page")
Fixes: 707c71a01b9d ("OvmfPkg: reserve SNP secrets page")

OvmfPkg/ResetVector: cache the SEV status MSR value in workarea
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3582
In order to probe the SEV feature the BaseMemEncryptLib and Reset vector
reads the SEV_STATUS MSR. Cache the value on the first read in the
workarea. In the next patches the value saved in the workarea will
be used by the BaseMemEncryptLib. This not only eliminates the extra
MSR reads it also helps cleaning up the code in BaseMemEncryptLib.

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.
