Summary:
The nested `.gitattributes` file in `packages/react-native-codegen/android/` caused some confusion on Linux and macOS, causing Git to show `packages/react-native-codegen/android/gradlew.bat` as modified (CRLF removed, LF added).
Instead of relying on repo-local `.gitattributes` files to convert endings in the working directory, the files should be committed to source control with the correct line endings in the first place. There is no reason to convert LF endings in .sh and many other file to CRLF on Windows (maybe this was an issue a long time ago, but unless Notepad is used this won't be a problem for practically all modern editors).
Also fixed the line endings of `scripts/launchPackager.bat` which was incorrectly committed as LF.
## Changelog

Summary: This diff moves the React Native template from `local-cli/templates/HelloWorld` to `template`. Keeping it in the react-native repo will allow us to make changes to the template and version it together with react-native, instead of moving it out into a separate repo and trying to keep the template in sync with RN.
