[vulkan] Implement view model rendering
Quake just looked wrong without the view model. I can't say I like the way the depth range is hacked, but it was necessary because the view model needs to be processed along with the rest of the alias models (didn't feel like adding more command buffers, which I imagine would be expensive with the pipeline switching).
