[ADD] website_sale_slides: allow to sell slide.channel

Task #1937160

Purpose
=======

This commit adds sale capabilities to a slide.channel. A slide.channel can
now have the 'payment' visibility, that requires a 'product_id' configured
on the channel.

When a customer purchases a product linked to a channel, he is added to the
members of the channel (see slide.channel.partner_ids) when his order is
confirmed.

The feature is added in a new module 'website_sale_slides' that comes as a
bridge auto-installed between 'website_slides' and 'website_sale'.

The final goal is to be able to sell "courses" (see task #1902304).
