Migrated Alert/*.js and ActionSheetIOS/*.js to use export syntax. (#48703)

Summary: Pull Request resolved: #48703 ## Motivation Modernising the react-native codebase to allow for ingestion by modern Flow tooling ## This diff - Updates files in Libraries/Alert and Libraries/ActionSheetIOS 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 of the related modules - Updates the public API snapshot (intented breaking change) Changelog: [General][Breaking] - Files inside `Libraries/Alert` and `Libraries/ActionSheetIOS` use `export` syntax, which requires the addition of `.default` when imported with the CJS `require` syntax.
