We only need one realize function per renderer backend. This may seem a bit odd to traditional QOM users since we mutate class function pointers, but the distinction between .instance_init and .realize is often tricky. A rule of thumb suggested by Liviu Ionescu is that is "instance_init ensures that all members have default values and properties associated with them, and defer all functional initialisations to .realize". I believe this patch does this. This refactoring will allow non-virgl 3D backends, without the need of a separate another virtio-gpu device and it's (vga, pci) variants.
