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: Add ability to run shaders This heaves over an inital chunk of code from the Vulkan renderer to execute shaders. The only shader that exists for now is a shader that draws a single texture. We use that to replace the blit op we were doing before.

gpu: Introduce the concept of "variation" A variation is a #define/specialization constant that every shader can use to specialize itself as it sees fit. This commit adds the infrastrcture, future commits will add implementations.

gpu: Reorganize format handling Add GSK_GPU_IMAGE_RENDERABLE and GSK_GPU_IMAGE_FILTERABLE and make sure to check formats for this feature. This requires reorganizing code to actually do this work instead of just pretending formats are supported. This fixes GLES upload tests with NGL.
