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: Refactor image handling Introduce a new GskGpuImageDescriptors object that tracks descriptors for a set of images that can be managed by the GPU. Then have each GskGpuShaderOp just reference the descriptors object they are using, so that the coe can set things up properly. To reference an image, the ops now just reference their descriptor - which is the uint32 we've been sending to the shaders since forever.

gpu: Setup attribute locations Make the generator generate calls for the correct glBindAttribLocation() calls. Usually this was done correctly, but we can't rely on it. So do it explicitly.
