fix(inspector_modules): Switch to single runtime chunk

The default setting causes the WebPack runtime to be loaded twice
because the `inspector_modules` module is loaded by the iOS runtime
as a secondary entry point. This has some undesirable implications
as [stated in the documentation](https://webpack.js.org/configuration/optimization/#optimizationruntimechunk):

> Imported modules are initialized for each runtime chunk separately,
> so if you include multiple entry points on a page, beware of this
> behavior. You will probably want to set it to single or use another
> configuration that allows you to only have one runtime instance.
