KVM: selftests: Add helpers to make Xen-style VMCALL/VMMCALL hypercalls
Add wrappers to do hypercalls using VMCALL/VMMCALL and Xen's register ABI
(as opposed to full Xen-style hypercalls through a hypervisor provided
page). Using the common helpers dedups a pile of code, and uses the
native hypercall instruction when running on AMD.
