Introduces a hierarchical structure of some menus. Reasons:
1. Allows testing the child-parent relation of specifically those menus
that do not have `parent` or `parent_id` attribute in the source xml
using standard menus. It's likely a rare use case, but that's precisely
what we currently need in https://github.com/odoo/upgrade/pull/5163
2. Provides a unique example usage of menus written in this manner
as opposed to using the `parent` attribute
