Amjad Masad 56d6ee3f0f [react-native] Replace jstransform with Babel in the OSS repo
Summary:
@public
Replaces jstransform with Babel. Additionally, stops (using the deprecated) passing an error property
back from the transformer, and instead passes an error in the first argument. This is because we were
able to update node-worker-farm to handle custom properties on errors.

Test Plan:
1. Export the oss project
2. npm install
3. Start the movies app
4. Make sure it works
5. Add a syntax error
6. Make sure the message is correct
