radv: status update or is Talos Principle rendering yet?

The answer is YES!!



I fixed the last bug with instance rendering and Talos renders great on radv now.



Also with the semi-interesting branch vkQuake also renders, there are some upstream bugs that needs fixing in spirv/nir that I'm awaiting and upstream resolution on, but I've included some prelim fixes in semi-interesting for now, that'll go away when upstream fixes are decided on.



Here's a screenshot:
