Integrate with React Native Web polyfills

There's been a few efforts to port various React Native APIs to work purely in the browser. It would be super useful if this IDE had the ability to build a project that made use of one or more of these to enable people to create apps that work not only on iOS and Android, but also anywhere that can run a browser.

The libraries that I've seen that seem most appealing are:

[react-web](https://github.com/taobaofed/react-web) Pretty good feature richness, seem to have some own ideas how building should be done. Developers seem to be primarily Chinese so it might have some language barriers if support is needed. Seems to have company backing which is good.
[react-native-web](https://github.com/taobaofed/react-web) Fewer components but the docs are nice and use React Storybook for quick references on how they work, but doesn't seem to have particularly detailed docs. Seems to mostly be run by one person in their spare time.
[react-native-for-web](https://github.com/KodersLab/react-native-for-web) Seems to be the least polished of the bunch, but could still be a viable option. More text docs than `react-native-web`

Obviously this would be a pretty big undertaking, but if this project had something like this it would be very unique in the ecosystem and could be immensely useful for cross platform development.
