CIF-2262: use Adobe AEM SEO api for product and category pages

[Buuhuu]

Description

This PR implements canonical link handling by using the mechanisms already in place for product and category sitemaps. Furthermore it implements the alternate language links for product/category pages in order to prevent the WCM Core Components Page behaviour to be in place.

This PR also annotates the model interface in ...models.page, ...models.product and ...model.productlist as ConsumerType.
