gpu: Add outline of new GPU renderer For now, it just renders using cairo, uploads the result to the GPU, blits it onto the framebuffer and then is happy. But it can do that using Vulkan and using GL (no idea which version). The most important thing still missing is shaders. It also has a bunch of copy/paste from the Vulkan renderer that isn't used yet. But I didn't want to rip it out and then try to copy it back later

gpu: Improve memory handling on Vulkan We now handle the case where memory is not HOST_CACHED. We also track the memory type now so we can avoid mapping image memory that is not HOST_CACHED and use buffer transfers instead.
