## Summary Right now image nodes hardcode logic to use either PINRemoteImage or the basic image downloader. Additionally, Texture is missing annotations for nullability and sendable for several of the image blocks and types. Introduce ASDefaultImageDownloader as a singleton. It takes blocks to return the default image downloader and image cache. Update both image nodes to use this. By default ASDefaultImageDownloader uses the same logic the image nodes used to, so change in behavior. ## Test plan Run the Kittens example and verify it works.

Summary
Right now image nodes hardcode logic to use either PINRemoteImage or the basic image downloader. Additionally, Texture is missing annotations for nullability and sendable for several of the image blocks and types.
Introduce ASDefaultImageDownloader as a singleton. It takes blocks to return the default image downloader and image cache. Update both image nodes to use this. By default ASDefaultImageDownloader uses the same logic the image nodes used to, so there's no change in runtime behavior.
