Permissions for Split inventory

Please update permission checks for Inventory > Split inventory. We now have a special SecurityAction.SplitInventory and it has to be replaced with SecurityAction.InventoryData.

Split inventory requires that users have CREATE permission SecurtyAction.InventoryData on the target site of the new inventories, and WRITE permission SecurtyAction.InventoryData on the site of the source inventory. Please update the API. Drop SecurityAction.SplitInventory and delete any permissions that exist for this action.

The UI should show this menu option only if the user has CREATE permission SecurtyAction.InventoryData on some site.
