x86 hvm: implement HVMOP_pagetable_dying

This patch implements HVMOP_pagetable_dying: an hypercall for
guests to notify Xen that a pagetable is about to be destroyed so that
Xen can use it as a hint to unshadow the pagetable soon and unhook the
top-level user-mode shadow entries right away.

Gianluca Guida is the original author of this patch.
