Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/51633 To fully support props diffing for a component, the component's Props implementation needs to implement the prop diffing for the derived class. Because all Props classes extend the ViewProps, all Props classes implement the `getDiffProps` function. To support testing that the props diffing implementation support all properties of the derived Props class for the component being mounted, this diff adds the virtual function `getDiffPropsImplementationTarget` which returns the `ComponentName` that the `getDiffProps` function supports. This removes the need for a hard-coded list of components that support props diffing and enables the use of codegen to conditionally enable props diffing.
