hyperv: process SIGNAL_EVENT hypercall
Add handling of SIGNAL_EVENT hypercall. For that, provide an interface
to associate an EventNotifier with an event connection number, so that
it's signaled when the SIGNAL_EVENT hypercall with the matching
connection ID is called by the guest.
Support for using KVM functionality for this will be added in a followup
patch.
