[16.0][IMP] purchase_sale_stock_inter_company: make pickings link configurable

[ACheung-FactorLibre]

This changes implement a configuration in the intercompany processes to determine whether the automatic processing of incoming shipments applies or not. By default, it should be disabled to allow independent management of shipments.

I have tested this feature in runbot. When you have the check "Link Purchase and Sale Pickings" activated, whenever you have intercompany transactions, these are linked. I have tried buying a product from My company (San Francisco) to My company (Chicago). When I create the purchase order on SF, a sale quotation is created on Chicago. When I create a backorder for the delivery, automatically this is translated to my purchase order in SF (moving to done the first receipt and creating a new partial reception with the remaining units)

With the new feature, you can deactivate the check "Link Purchase and Sale Pickings" so that one move is independent from the other. This is useful if you want to have full trace of your receptions and you don´t want things confirming on its own. I have done the same process as before, but without the check.
