KVM: SVM: Add support to handle GHCB GPA register VMGEXIT
SEV-SNP guests are required to perform a GHCB GPA registration. Before
using a GHCB GPA for a vCPU the first time, a guest must register the
vCPU GHCB GPA. If hypervisor can work with the guest requested GPA then
it must respond back with the same GPA otherwise return -1.
On VMEXIT, Verify that GHCB GPA matches with the registered value. If a
mismatch is detected then abort the guest.
