Proposal: Adjust representation of Regions in the Layers UI

Overview

In the designs, the way Regions are represented differs from the current codebase. In the code, currently, the Layers panel is basically a 1:1 representation of how the Regions/Components data is organised in JSON. In Figma, the design shows Regions as siblings of the components in the current Content block.

Proposed resolution

I think, before the work is undertaken to implement the UI as shown in the design there should be discussion around abstracting the regions view in this way vs keeping it closer to the data model representation.
