haven: Align APIs and structures to account for the mem_info tag
The memory information tag is meant to be used in conjunction with the memory notification interfaces to associate a label or tag with a memory parcel. This memory information tag is meant to be used for distinguishing between different memory resources that can be transferred between Virtual Machines (VMs).
