This is v12 of the TDX selftests.

This series is based on v6.18-rc3

Changes from v11 [1]:
- Rebased on top of v6.18-rc3.
- Hook vm_tdx_finalize() into kvm_arch_vm_finalize_vcpus instead of
  calling it as part of vm_tdx_create_with_one_vcpu. See "KVM: selftests:
  Finalize TD memory as part of kvm_arch_vm_finalize_vcpus" which was
  added to this series.
- Replaced vm_tdx_create_with_one_vcpu with vm_create_shape_with_one_vcpu
  following Sean's patch to simplify creating VM shapes.
