Add Hyper-V specific code so that a fully enlightened TDX guest (i.e. without the paravisor) can run on Hyper-V: Don't use hv_vp_assist_page. Use GHCI instead. Don't try to use the unsupported HV_REGISTER_CRASH_CTL. Don't trust (use) Hyper-V's TLB-flushing hypercalls. Don't use lazy EOI. Share the SynIC Event/Message pages with the hypervisor. Don't use the Hyper-V TSC page for now, because non-trivial work is required to share the page with the hypervisor.
