[RFC PATCH v3 04/59] KVM: TDX: Add TDX "architectural" error codes

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

Add error codes for the TDX SEAMCALLs both for TDX VMM side and TDX guest
side.

TDX SEAMCALL uses bits 31:0 to return more information, so these error
codes will only exactly match RAX[63:32]. Error codes for TDG.VP.VMCALL is
defined by TDX Guest-Host-Communication interface spec.
