This patchset introduces the modifiers support to virtio-gpu.
This RFC version tries to add a new virtio-gpu command to let front-end driver query the modifiers' info from the backend. Besides, the front-end driver may also need a new drm helper function to add the supported modifiers to a plane as its properties and allow fbs to use modifiers on that plane.
