Use a new algorithm for placement of new nodes in cases when:
- a) there is no selected node, and the `TAB` key is pressed while the mouse pointer is near an existing node (especially in an area below an existing node);
- b) a connection is dragged out from an existing node and dropped near the node (especially in an area below the node).
In both cases mentioned above, the new node will now be placed in a location suggested by an internal algorithm, aligned to existing nodes. Specifically, the placement algorithm used is similar to when pressing `TAB` with a node selected.

# Important Notes
- Visible visualizations enabled with the "eye icon" button are treated as part of a node. (In case of nodes with errors, visualizations are not visible, and are not treated as part of a node.)
* Creating a new node with the (+) button (#3278)
[The Task](https://www.pivotaltracker.com/story/show/180887253)
A new (+) button on the left-bottom corner appeared. It may be clicked to open searcher in the middle of the scene, as an alternative to tab key.

* The window_control_buttons::common was extracted to separate crate `ensogl-component-button` almost without change.
* This includes a severe refactoring of adding nodes in general in the Graph Editor. The whole responsibility of adding new nodes (and starting their editing) was moved to Graph Editor - the Project View only reacts for GE events to show searcher properly.
* The status bar was moved from the bottom-left corner to the middle-top of the scene. It does not collide with (+) button, and plays "notification" role anyway.
* The `interface` debug scene was buggy. The problem was with one expression's span-tree. When I replaced it, the scene works.
* I've removed "new searcher" API, as it is completely outdated.
* I've changed code owners of integration tests to GUI team, as it is the team writing mostly the integration tests (int rust)
* Fix regression #181528359
* Add docs & remove unused function
* Fix & enable native Rust tests
* Fix formatting

[ci no changelog needed]
This PR reverts commit [0836ce741d](0836ce741d) because of the spotted regression:
To reproduce:
1. Open a default project.
2. Without doing anything else, cmd + click on any node to edit it.
3. Abort editing by pressing escape.
4. Top-most node disappears (it is actually removed from scene)
If you start editing the bottom node - you will also see a visible regression in node searcher's position.
