[FIX] mrp: calculate produced quantity based on free subcontractor stock

The free to produce quantity was calculated based on the available stock in the warehouse in addition to the subcontracting location. For this reason, `free_to_manufacture_qty` variable was introduced. If it is a non-subcontracting BoM, it will be equal to the free quantity available in warehouse stock. Otherwise, it will contain only the stock in the subcontracting location.
