[vulkan] Start moving towards a deferred renderer After getting lights even vaguely working for alias models, I realized that it just wasn't going to be feasible to do nice lighting with forward rendering. This gets the bulk of the work done for deferred rendering, but still need to sort out the shaders before any real testing can be done.
