Revert "PERF: Update ember-auto-import (#15814)" (#15854)

This reverts commit f4c6a6185517a7d8a17c3faefb7e2e8cc67c44a8 and a8325c9016230f5171e0b72d7bff069784f64d16

This update of ember-auto-import and webpack causes significantly higher memory use during rebuilds. This made ember-cli totally unusable on 1GB RAM / 2GB swap environments. We don't have a specific need for this upgrade right now, so reverting for now.
