[turbopack] Sort modules in files by path not ID (#95065)
Sorting-by-ID was flagged as bad for g-zipping:
> This sorts by chunk item id.
> Tobias has been saying that this is bad, because it gzips worse
> We should be sort by path, so that similar modules stay together. E.g.
if you have many similar icon modules
> Sorting by chunk item results in random order
Switched to sorting by path!
