Vulkan: Minimal dirty bits for ContextVk. Currently this won't speed up performance much, if at all, since we don't even really support state changes. It sets the stage for using a pipeline cache later, with better state change support. It also makes implementing descriptor sets for Textures a bit simpler, since we can just update descriptor sets when the dirty bits tell us of a Texture change. Add cache structures to VertexArrayVk and ContextVk so we only need to update the structures before we create a new pipeline. When we support pipeline caching, we will most likely be updating a compact representation for fast cache query.
