Summary: Allow JS to detect if a native UI component is registered to `RCTComponentViewFactory.mm` with JS `UIManager.hasViewManagerConfig(componentName)`. Fyi, `UIManager.js` is - `DummyUIManager.js` for Bridgeless, - `LazyUIManager.js` for Fabric with SVC enabled, - and `PaperUIManager.js`. for Fabric with SVC disabled. # How it works in Bridgeless - `DummyUIManager.hasViewManagerConfig()` checks whether a component exists in the binary. It is hooked up to `unstable_hasComponent()`, - which is hooked up to the native function `RCTInstallNativeComponentRegistryBinding()`, - which returns whether a component has been registered to `RCTComponentViewFactory` - (and also registers the native component if hasn't been registered yet).
