Make the display handle the cache, because we only need one. We store the cache in $CACHE_DIR/gtk-4.0/vulkan-pipeline-cache/$UUID.$VERSION so we regenerate caches for each different device (different UUID) and each different driver version. We also keep track of the etag of the cache file, so if 2 different applications update the cache, we can detect that. Vulkan allows merging caches, so the 2nd app reloads the new cache file and merges it into its cache before saving.
