KVM: TDX: Handle TDG.VP.VMCALL<GetTdVmCallInfo> hypercall
Implement TDG.VP.VMCALL<GetTdVmCallInfo> hypercall. If the input value is
zero, return success code and zero in output registers.
TDG.VP.VMCALL<GetTdVmCallInfo> hypercall is a subleaf of TDG.VP.VMCALL to
enumerate which TDG.VP.VMCALL sub leaves are supported. This hypercall is
for future enhancement of the Guest-Host-Communication Interface (GHCI)
specification. The GHCI version of 344426-001US defines it to require
input R12 to be zero and to return zero in output registers, R11, R12, R13,
and R14 so that guest TD enumerates no enhancement.
