[vulkan] Reduce max shadow views to 17

Browse source 
Recent nvidia drivers now crash with more than 17 views when building
pipelines. Still no idea if it's me or the drivers. However, I really
need to come up with a way to use the render graph render passes as a
template so things aren't so hard-coded.
