DevTools shared Babel config previously supported IE 11 to target Hermes (for the standalone backend that gets embedded within React Native apps). This targeting resulted in less optimal code for other DevTools targets though which did not need to support IE 11. This PR updates the shared config to remove IE 11 support by default, and only enables it for the standalone backend target.
* DevTools console override handles new component stack format
DevTools does not attempt to mimic the default browser console format for its component stacks but it does properly detect the new format for Chrome, Firefox, and Safari.
* Add version 4 react-devtools and react-devtools-core packages which support both React Native and e.g. Safari or iframe DOM usage.
* Replaces typed operations arrays with regular arrays in order to support Hermes. This is unfortunate, since in theory a typed array buffer could be more efficiently transferred between frontend and backend for the web extension, but this never actually worked properly in v8, only Spidermonkey, and it fails entirely in Hermes so for the time being- it's been removed.
* Adds support for React Native (paper renderer)
* Adds a style editor for react-native and react-native-web
