In many browsers (other than Chrome), the `alt` text is visible while the image is loading. This causes a sense layout shift since you'll see a flash of text and then the image (although lighthouse measures 0 CLS, likely because Chrome doesn't have this problem). This PR updates `next/future/image` to hide the alt text, unless there is an error while loading the image in which case the `alt` text because relevant as the fallback. Example: <img width="115" alt="image" src="https://user-images.githubusercontent.com/229881/183128008-0660c50c-18aa-4e64-872e-ada9a652130f.png"> Unfortunately, Safari also shows a border while lazy loading images and it cannot be styled.
