Order item theme suggestions

No reason not to add this template.

Problems:

1. We don't prefix our entities and render arrays with commerce_ in templates. So we want just order_item and order_item_entity.

2.

+  $purchased_entity = $commerce_order_item->getPurchasedEntity();
+  $variables['purchased_entity'] = $purchased_entity;
+  $product = $purchased_entity->getProduct();
+  $variables['product_entity'] = $product;

I don't think we should do this. The template can easily do {{ order_item_entity.getPurchasedEntity.getProduct.something }} when needed.

Thank you for the provided patch.

The patch works as expected, but there is a mistake made in #8. The theme variables became "order_item" but in template still used "commerce_order_item". So, I changed in patch #8 and sure it can be marked as RTBC.

Both patches don't apply any more.

Same patch with updated line index, should apply cleanly now.

Patch now applies cleanly, moving back to RTBC

Confirming the patch #13 works fine.

Thanks! 🥳 commited.
