Original issue's description:
> DevTools: Introduce module initializers
> 
> For all lazy-loaded modules and workers, _module.js files are introduced, which
> importScript() all scripts for a particular module.
> 
> This allows to:
> - get rid of importScript() calls intertwined with meaningful code,
> - simplify module loading, since Runtime does not need to read the
>   module descriptor to determine the resource names.
> 
> This approach is similar to how we implement
> the CSS loading in inspector.css.
