See together with #10837

Refactor the spacing among the elements of the different redesign layouts: https://github.com/decidim/decidim/tree/feature/redesign/decidim-core/app/views/layouts/decidim/shared

We should wrap each block through section tags or similar, in order to keep spacing consistency all around. Apply both main and aside, if apply.

The aim is avoiding specific margins/paddings in the views, handling that in decidim-core/app/packs/stylesheets/decidim/_redesigned_layout.scss instead
