dm: virtio-gpu: basic framework

Browse Source 
Virtio-gpu is a virtio based graphic adapter. It supports 2D mode
which can transfer the guest vm's framebuffer into service vm's
buffers for displaying. It can co-work with Intel GPU VF(SRIOV)
device and provide thransport for the accelerated contents. With
this, guest vm can benefit Intel GPU hardware to accelerate media
coding, 3D rendering and compute.
