chore(product): revamp upsertWithReplace and Remove its usage from product creation (#11585)

**What**
- Move create product to use native create by structuring the data appropriately, it means no more `upsertWithReplace` being very poorly performant and got 20x better performances on staging
- Improvements in `upsertWithReplace` to still get performance boost for places that still relies on it. Mostly bulking the operations when possible
