[PATCH v1 2/6] hyperv: Add two new hypercall numbers to guest ABI public header

In preparation for the subsequent crashdump patches, copy two hypercall
numbers to the guest ABI header published by Hyper-V. One to notify
hypervisor of an event that occurs in the root partition, other to ask
hypervisor to disable the hypervisor.
