feat(infra): add framebuffer/DRM/VirtIO GPU 3D acceleration

Browse source 
hardware.virtio.enable + guestAgent (QEMU guest agent for SCP).
services.xserver with virtiogpu + fbdev + vmware video drivers.
services.spice.enable with vdagent.

Packages: mesa, libGL, libGLU, virglrenderer (VirtIO-gpu 3D),
swiftshader (software Vulkan), libva (VA-API), spice, spice-gtk,
xorg.libX11/ext/render, xf86-video-vMware/fbdev.

Kernel modules: virtio-gpu, drm, drm_kms_helper, drm_shmem_helper, ttm.
