Allow other modules to work with the order and data post-creation, using alter hooks

Hello again, I've attached a new patch, which contains two new hooks: -

1. hook_decoupled_order_data_alter - allows the order data to be altered.
2. hook_decoupled_order_alter - allows the order to be altered. In my case we adding a shipment to the orders.

I've also moved the validation hook below the order_checkout_prepare hook so we can change the incoming data. In my case, the third party sends an EAN code as a lookup as opposed to the SKU, so we find the product variations that way and change the order data to have the skus instead.

Hi @Dubs, Thanks for this.

I've reviewed the patch, it has been applied smoothly, code changes look good, the module works normally, and no problems were found.

Thank you all for working on it! I have merged the path.
