Allow manufacturing orders to use the same product as both the finished good and a component when configured.

Features

res.config.settings: Adds a setting to enable using the same product as both component and finished product in manufacturing orders.
res.company: Stores the company-level flag controlling whether recursive product usage is allowed in production.
