Saving address form

Frontend

With business checkout there is an additional dropdown field in the forms:

It allows one to choose between private and business customer types:

There are business type-only fields: Company and VAT ID. They are shown when the business customer type is chosen and hidden when the private customer type is selected.

Company and VAT ID must be enabled in the admin panel (Stores -> Configuration -> Customers > Customer Configuration -> Name and Address Options) and Show VAT Number on Storefront ste to yes (in Show VAT Number on Storefront tab)

Customer Type is saved along with the address.
