Summary: Use Fabric layout data to classify image shadow nodes as visible or offscreen on Apple platforms. Offscreen image requests now use `ImageRequestPriority::Prefetch`, which is bridged to the existing `RCTImageLoaderPriorityPrefetch` API, while visible images stay at `Immediate`; the new React Native feature flag defaults to `false` until app-specific gating wires it up.
