[FIX] l10n_ar_website_sale: always display b2b fields for argentina

Steps to reproduce:

  - Install `l10n_ar_website_sale` module

  - Go to shop (Argentinian website) and add a product to cart
  - Open cart and click on checkout
  - Click on Customize and disable `Show b2b fields` feature

Issue:

  Fields are no more displayed.

Cause:

  Since the b2b fields template (`address_b2b`) have customize_show set
  to `True`, it is possible for all countries to display/hide
  the b2b fields, but it should not.

  For Argentinian companies (for example), the b2b fields should always
  be displayed.

Solution:

  For frontend (Website shop): in address form, if website company
  country is Argentina, check if the address_b2b view is active and if
  not, enable it.
  For frontend and backend: on write of a view `address_b2b`, do not
  allow to disable it if have a website and website company
  country is Argentina.
