Error in preview when using code splitting

[KutnerUri]

When using code splitting, webpack creates assets (*.chunk.[hash].js, etc), which are not picked up as component artifacts.
Then when loading the preview, the browser tries to load these chunks and fails with 404.

For example:
https://jw02b1z.scopes.teambit.cloud/api/teambit.react/react/~aspect/env-template/compositions/#teambit.community/apps/[email protected]?preview=compositions&BitDevBasic

by @GiladShoham, this is happening because we take a partial list from the Webpack "stats" output, as seen here:

bit/scopes/webpack/webpack/webpack.bundler.ts

Line 60 in d2b0ed7

const info = stats.toJson({

We need to:

• separate each chunk to output in its own folder (via the output.path option, or the output.filename option with a template string like "[name]/...". Note that we'd might also have to fill the other filename options too)
• load all files from the folder as artifcats
• somehow separate them when loading component preview (we only want the entry assets)
