virtio-gpu: move virgl realize + properties

Browse Source 
Move device init (realize) and properties.

Drop the virgl property, the virtio-gpu-gl-device has virgl enabled no
matter what.  Just use virtio-gpu-device instead if you don't want
enable virgl and opengl.  This simplifies the logic and reduces the test
matrix.
