SEV-SNP guests on Hyper-V can run at multiple Virtual Trust Levels (VTL). During boot, get the VTL at which we're running using the GET_VP_REGISTERs hypercall, and save the value for future use. Then during VMBus initialization, set the VTL with the saved value as required in the VMBus init message.
