[vulkan] Resurrect the forward render pass spec
It's not used yet, and thus may have some incorrect settings, but I decided that I will probably want it at some stage for qwaq. It's essentially was was in the original spec, but updated for some of the niceties added to parsing since I removed it back then. It's also in its own file.
