From: Sean Christopherson <sean.j.christopherson@intel.com>

Add TDX completion status codes for SEAMCALL and TDG_VP_VMCALL.

TDX-SEAM uses bits 31:0 to return more information, so these error codes
for SEAMCALL will only exactly match RAX[63:32]. [1] Section 17.1 Interface
Function Completion Status Codes
Completion status codes for TDG.VP.VMCALL is defined in
[2] Chapter 3 TDG.VP.VMCALL Interface.
