collab: Save Customer name and billing address to Customer on checkout (#33385)

We are collecting billing address and name on checkout now (for tax) but
we're not saving it back to the Customer level. Updating the Checkout
Session code to make`customer_update.address` equal to `auto`, instead
of the default `never`, as well as the same for `customer_update.name`.

Release Notes:

- N/A
