A framework for building native applications using React

Babel preset: Add unstable_preserveAsync to experiment with disabling async transforms for SH (#56254)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/56254

Disable `babel/plugin-transform-async-to-generator` and `babel/plugin-transform-async-generator-functions` when `customTransformOptions.unstable_preserveAsync` is truthy. This allows us to experiment with native async/await support in Static Hermes.
