Introduce the VirtioGpuAllocateZeroAndMapBackingStore() and VirtioGpuUnmapAndFreeBackingStore() helper functions. These functions tie together the allocation, zeroing and mapping, and unmapping and deallocation, respectively, of memory that the virtio GPU will permanently reference after receiving the RESOURCE_ATTACH_BACKING command. With these functions we can keep the next patch simpler -- the GOP implementation in "Gop.c" retains its error handling structure, and remains oblivious to VIRTIO_DEVICE_PROTOCOL and VirtioLib.
