KVM: VMX: Define a VMX glue macro for kvm_complete_insn_gp()
Define kvm_complete_insn_gp() as vmx_complete_emulated_msr() and use the
glue wrapper in vt_complete_emulated_msr() so that VT's
.complete_emulated_msr() implementation follows the soon-to-be-standard
pattern of:
vt_abc:
if (is_td())
return tdx_abc();
return vmx_abc();
This will allow generating such wrappers via a macro, which in turn will
make it trivially easy to skip the wrappers entirely when KVM_INTEL_TDX=n.
