[kvm-unit-tests PATCH 16/16] x86: Move SEV MSR definitions to msr.h

[Sean Christopherson]

Move the SEV MSR definitions to msr.h so that they're available for non-EFI
builds.  There is nothing EFI specific about the architectural definitions.

Opportunistically massage the names to align with existing style.

No functional change intended.
