Summary: Couldn't make RCTImageEditingManager and RCTImageStoreManager TurboModule-compatible because their specs live in fb-internal code. I will tackle them in a subsequent diff. See T54946472. Changelog: [iOS][Added] Make RCTLocalAssetImageLoader and RCTGIFImageDecoder TurboModule-compatible Reviewed By: PeteTheHeat Differential Revision: D17936483 fbshipit-source-id: 2266c9ea1ca7ecd52717d9a963e39245da312312
