Gorm Bad insertion IDs when doing a bulk Upsert

GORM Playground Link

https://github.com/go-gorm/playground/pull/658

When bulk inserting rows with a OnConflict / DoUpdates clause, generated IDs are wrong if the saved items are a mix of existing and new items.

The submitted PR case shows how to reproduce this.

Might be related to #6027, seems like we still see this on latest Gorm version. We have been stuck on v1.24.3 for a while now as a result
