Work in progress. Continued to clean up cross bundle dependencies on implementation classes, like ScopeRegistry, CompositeActivator, ContributionService, some of the factories. Added declarations of some of these utilities to the relevant modules. That also simplified the bootstrap of the runtime used by NodeImpl, which doesn't invoke all their constructors anymore.
