Add a new field to input.graphql to identify if the function is running in Draft Order context

[AndreaMorone]

Would it be possible to add a new field in the input.graphql schema to indicate if a function is running on a draft order or a normal checkout? This would provide greater control for customizations.

Should be a 0-cost field, ensuring no impact on existing logic builders or workflows.

This would allow precise logic targeting draft orders vs. normal checkouts (we are receiving a lot of requests from merchants that do not want run customizations in the Shopify admin).

I agree with @AndreaMorone
