Subject: [PATCH] Remove global babelHelpers and regenerator (#21283)

Summary:
Follow up to https://github.com/facebook/metro/commit/8932a9caa8f9ffe82160f2da25342a0bde3bbb26

Babel helpers and regenerator runtime will be imported automatically from `babel/runtime`. We still need to add the global regeneratorRuntime for jest tests since we disable babel-runtime currently.
Pull Request resolved: https://github.com/facebook/react-native/pull/21283
