x86/sev: Include XSS value in GHCB CPUID request
When a guest issues a CPUID instruction for Fn0000000D_x01, the hypervisor may
be intercepting the CPUID instruction and need to access the guest XSS value.
For SEV-ES, the XSS value is encrypted and needs to be included in the GHCB to
be visible to the hypervisor.
