[IMP] website_sale: don't show product from another website to admin

Before this commit, the alternatives products were not multi-website filtered
to the admin.
The suggested product were filtered by website thanks to the
`website_published` filter.
This only concern the admins, as for portal and public user, all of this is
done automatically by the ACLs anyway, where we force_domain to
`website_published` products, which also filter by website (see the mixin).

This will also eases module inheritance as we use `sale_product_domain()`.

Fixes #67501
