Summary:
This diff runs the codemod to add type annotations to function parameters in preparation for Flow's local type inference (LTI) project. I ran the codemod over xplat/js and reverted any files that had flow errors in them. See the list of commands run to see the regeneration of various files.

Summary:
In development, we can specify a debug name to force the whole React tree to have a meaningful name. This is useful for debugging: React DevTools, component stack traces, etc. More context in D26637787 (https://github.com/facebook/react-native/commit/eeb36f470929c2fdd8e1ed69898a5ba9144b8715).
This worked fine until now because `renderApplication` is never called more than once per React Native root. With pre-rendering, this won't be true as we'll be able to re-render the whole React tree with new props (after navigating to the screen).
The problem with the current implementation is that we generate a new component every time `renderApplication` is called, which makes the React reconciliation consider them different components and discards the whole sub-tree.
This fixes it by caching those components so we always return a component with the same identity (exactly the same function) when we call `renderApplication` repeatedly.
This won't have any effect in production where these components aren't created at all.
