[FIX] website_sale: publish product after creation

This is a follow-up for the task: 3977931.

In this commit, we make sure that the
`product.product_product_view_form_normalized`, which is the common form view
used to create a product on-the-fly from different modules, includes the Website
Category field and if it's filled, the product is automatically
`website_published`.

We accomplish this by moving the `public_categ_ids` field from
`website_sale.product_product_view_form_normalized_website_sale` to
`product.product_product_view_form_normalized`.

NOTE that `website_sale.product_product_view_form_normalized_website_sale`
should be present and remained the view used by website_sale since it uses the
`website_new_content_form` custom form view.
