What?

This fixes more CSS ordering issues with production and webpack dev.

  • CSS Modules must not be side effect free as side effect free modules are per definition order independent which is not true for CSS
  • fix order of iterating module references
  • disable splitChunks for CSS
  • special chunking for CSS with loose and strict mode
  • more test cases

Closes PACK-2709
