[fix] ImageLoader images are not added to ImageUriCache

Previously loaded images used to be added to ImageUriCache
It seems the logic was accidentally removed here: f4e8b6b#diff-7cb74a3a32d73857be80350ecd1ea131d256bd5af11d2000e4fc2d03c2230584L361

And now the `ImageUriCache` is only updated by preload/getSize

packages/react-native-web/src/modules/ImageLoader/index.js
