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).
