Switch virtio-wl to the new shared memory APIs. Using the shared memory APIs requires establishing mappings based on shm offset rather than raw pfn. This means virtio-wl needs to manage its shmem address space itself, rather than relying on VmMemoryDestination::NewAllocation. To maintain compatibility with older drivers, a feature bit is used to determine whether drivers expect mappings to be specified by shm offset or by pfn.
