Introduces a new configuration for the `ng-dev release` command. This
configuration will be the source of truth for all release packages
and how they can be built.
Additionally, in a temporary manner where each project has its own
way of generating the changelog, the changelog generation can be
configured. This will be removed in the future when there is
canonical changelog generation in the dev-infra shared package.
