Now all of the chunking context functions accept ChunkGroup

The names are bad, but entry_chunk_group and ChunkGroup::Entry have nothing to do with each other:

  • entry_chunk_group means: it's a standalone file where node path/to/chunk.js will execute it
  • ChunkGroup::Entry = it's the top-level chunk group

For example a evaluated_chunk_group(ChunkGroup::Entry) is also fine
