gpu: implement virtio-gpu
Basic 2D and 3D support is there. The drm_cursor_test and
null_platform_test in drm-tests should run to completion.
The extra device is hidden behind both a build time feature called 'gpu'
and the device is only added to a VM if the '--gpu' flag is given.
TEST=build with --features=gpu;
drm_cursor_test && null_platform_test
