[vulkan] Start work on shadows
This gets the shaders needed for creating shadow maps, and the changes to the lighting pipeline for binding the shadow maps, but no generation or reading is done yet. It feels like parts of various systems are getting a little big for their britches and I need to do an audit of various things.
