In order to know that global features are contributed in project dependencies, we'll need to add an entry in the studio registries for the global contribs.
=> Instead of using features id, we use their type.
=> we just need a boolean to know if a contrib of this type exists
What we want to do with this info:
- override icon if global feature is overridden in current project
- override info even if the global feature is not contributed in current project
- warning when User/Group editor is open: Almost same message than when feature is created locally
