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

This reverts commit f4c6a61855 and a8325c9016

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.
