virtio-gpu-udmabuf: correct naming of QemuDmaBuf size properties

Replace 'width' and 'height' in QemuDmaBuf with 'backing_widht'
and 'backing_height' as these commonly indicate the size of the
whole surface (e.g. guest's Xorg extended display). Then use
'width' and 'height' for sub region in there (e.g. guest's
scanouts).
