[tech] global - Review package structure to split common from component specific items

[pegros]

The objective is to split the common force-app/main/default folder in separate ones to isolate and better manage dependencies, e.g. when a wishing to deploy only a subset of components.

Target would be to have a common folder with the base elements and folders by App Builder component grouping all their specific items.

Please refer to what has been done on the PEG_MISC and PEG_CRMA repositories.
