Migrate AppState and BatchedBridge files to use export syntax.

Summary: ## Motivation Modernising the react-native codebase to allow for ingestion by modern Flow tooling. ## This diff - Updates files in Libraries/AppState and Libraries/BatchedBridge to use `export` syntax - `export default` for qualified objects, many `export` statements for collections (determined by how it's imported) - Appends `.default` to requires of the changed files. - Updates Jest mocks. - Updates the public API snapshot (intented breaking change) Changelog: [General][Breaking] - Files inside `Libraries/BatchedBridge` and `Libraries/AppState` use `export` syntax, which requires the addition of `.default` when imported with the CJS `require` syntax.
