This PR provides a visual indication of whether the project's current state differs from the most recent snapshot saved in the VCS. The project name displayed in the IDE changes to a darker text to indicate that the VCS snapshot is outdated, and back to a lighter text when the current project state corresponds to the last saved VCS snapshot.
https://user-images.githubusercontent.com/117099775/208088438-20dfc2aa-2a7d-47bf-bc12-3d3dff7a4974.mp4
The outdated project snapshot indicator is set when:
* A node is moved.
* A node is added or removed.
* The text editor is used to edit the text.
* The project is auto-saved, and the auto-saved project state does not correspond to the last saved snapshot in the VCS.
The outdated project snapshot indicator is cleared when:
* A new project snapshot is successfully saved using `ctrl+s`.
* The project is auto-saved, and the auto-saved project state is confirmed to correspond to the last saved snapshot in the VCS. This occurs, for example, when a project change is undone and the project is reverted to the last saved snapshot state.
The auto-save events do not occur immediately after a project change but have a short delay, thus the VCS status update is affected by the same delay when triggered by an auto-save event.
This PR introduced an overhauled Component List Panel implementation, making use of the efficient EnsoGL grid view component. Also, it delivers a couple of new features:
* A part of the new design: there are no more section headers in grid, instead groups are "glued" together. The local scope section is under "popular" (old "favorites").
* The keyboard management inside grid works.
* there is a mouse hover highlight
* selecting the lowest entry in section when jumping with navigation bar.
* accepting input as-is with cmd/ctrl + Enter.

### Important Notes
**What is not implemented:**
* [Focus management between panels.](https://www.pivotaltracker.com/story/show/180872763) The grid is always focused. To accept the current input, use ctrl+Enter shortcut.
* [Proper handling of selection when having empty space on the right and pressing right arrow.](https://www.pivotaltracker.com/story/show/183487880)
* When entering a module, its name is not added to the input as described in the design doc. Will be a part of [this User Story](https://www.pivotaltracker.com/story/show/181058321).
**Known issues**
* [the selection, especially in the local scope section, has sometimes an undesirable offset](https://www.pivotaltracker.com/story/show/183487730). The cause is known, but not so easy to fix.
* The inserted nodes are often producing errors. The Browser's inherits the outdated understanding of the language from old Node Searcher, and it does not include new form of imports, static methods etc. Those all will be fixed as a part of [this User Story](https://www.pivotaltracker.com/story/show/181058321).
* The performance is improved, but still not ideal, due to problems in [text areas](https://www.pivotaltracker.com/story/show/183406745).
* To scroll the documentation panel, you must first click on it.

This PR implements a Breadcrumbs panel for the new component browser.
The Breadcrumbs is a horizontal list of text labels separated by a special icon and has an optional ellipsis icon at the end.
It is implemented using the new GridView component.

# Important Notes
- This PR implements an old interaction of the design of the component browser. The new design of the breadcrumbs can not be easily integrated into the current look of the component browser, so we would need to update styles later. It should be a relatively simple task. *The implementation uses color from the new design though. (but not fonts and sizes)*
- I found a bug in the grid view implementation that causes panics at runtime in some conditions. The reason is triggering FRP endpoints while constructing new entries. This issue is fixed in the PR.
This PR contains all work for finishing integration of first Component List Panel in the IDE:
* It adds a stub for the whole Component Browser View. The documentation panel is re-used from the old searcher.
* It has the presenter implementation, integrating the view with Hierarchical Component List from the controller.
* It extends the View API, so the integration is possible, making use of Component Group Set wrapper.
* The selection integration was also merged into this PR, because it depended on the API extension mentioned above. However, we should avoid such practice in the future.

# Important Notes
There are some known issues, to-be-fixed in the future.
* The performance is bad. It should be improved with new text::Area, and the decent one shall come with [GridView inside component browser](https://www.pivotaltracker.com/story/show/182561072)
* There is no keyboard navigation. It should also be delivered with [GridView](https://www.pivotaltracker.com/story/show/182561072).
* The Favorites section is not [filtered out by node source type](https://www.pivotaltracker.com/story/show/182661634).
If a node created by the user gets placed off-screen, the screen's camera is panned to make the node visible.

# Important Notes
- Camera is panned also if the node is only partially visible, or if there's not enough free space visible around the node. The specific amount of free space that needs to be visible around a newly created node is configured in the theme.
- If the screen area is so small that the node cannot be fully fit in it (either horizontally or vertically), showing the left and top boundaries of the node's area takes priority over showing the corresponding opposite edges.
Implement simple placeholder icons for all entry kinds supported in the Suggestion Database. The icons are planned to be used in Component Browser as default icons for entries. This is intended to allow visually distinguishing different entry kinds.
The following additional fixes and tweaks are applied:
- Icons previously using only 1 color from the theme now use the color provided through shape parameters instead.
- The `data_science` and `network` icons now use only the 2 colors provided through shape parameters.
- The `join` icon has its shape and colors modified and uses only the 2 colors provided through shape parameters.
- The demo scene now parametrizes icon shapes using colors from the Component Browser Design Doc.

This PR implements a new selection box that will replace an old (not really working) one in the component browser. The old selection box wasn't working well with the headers of the component groups, so we were forced to make a much harder implementation.
The new implementation duplicates some visual components and places them in a separate layer. Then, a rectangular mask cuts off everything that is not "selected". This way:
- We have more control over what the selected entries should look like.
- We can easily support the multi-layer structure of the component groups with headers.
- We avoid problems with nested masks that our renderer doesn't support at the moment.
To be more precise, we duplicate the following:
- Background of the component group becomes the "fill" of the selection.
- Entries text and icons - we can alter them easily.
- Header background and header text. By placing them in separate scene layers we ensure correct rendering order.
https://user-images.githubusercontent.com/6566674/173657899-1067f538-4329-44f9-9dc2-78c8a4708b5a.mp4
# Important Notes
- This PR implements the base of our future selection mechanism, selecting entries with a mouse and keyboard still has several issues that will be fixed in the future tasks.
- The scrolling behavior will also be improved in future tasks. Right we only restrict the selection box position so that it never leaves the borders of the component group.
- I added a new function to `add` shapes to new layers in a non-exclusive way (we had only `add_exclusive`) before. I have no idea how we didn't use this feature before even though we mention it a lot in the docs.
- The demo scene restricts the position of the selection box for one-column component groups but does not for the wide component group.
This PR extends the Component Group Entry with icon and option to highlight the text. Here the convert has highlighted "con".

### Important Notes
Although this PR includes effort for adjusting Component Group style to better reflect the design, it is not entirely finished: the selection still works badly and will be fixed in another PR.
[ci no changelog needed]
[Task link](https://www.pivotaltracker.com/story/show/181725003)
This PR implements a fully visible component group header while scrolling the group (using the ScrollArea).
The header moves in sync with scrolling movements (using new `set_header_pos` FRP input), so it looks like the component group is scrolled. ScrollArea masks the "scrolled" entries above the header. This design allows a fully visible header even though our renderer doesn't support nested layers masking yet.
The screencast:

# Important Notes
- I fixed the API of the list view so now it supports non-hardcoded scene layers (previously it did not). I also believe it was implemented incorrectly.
- I've found a [pretty weird bug](https://www.pivotaltracker.com/story/show/182193824): the component group inside the ScrollArea is invisible unless I add some arbitrary shape to the scroll area content. I use a `transparent_circle` for this purpose in the demo scene. The bug is probably related to masking the sublayers, though I wasn't able to reproduce it properly on a simpler example.
- The selection box is removed from the demo scene as agreed with @farmaazon . The correct implementation has proven to be much harder than I expected, and we will implement another approach in a separate PR.
- I also modified the `shadow::Parameters` so that it uses `Var`s instead of plain values.
Parametrize the colors used in a Component Group view based on a single color passed to an FRP input.
Customizing the colors of a Component Group will be needed for the larger Component Group List panel. This customization will work as a visual hint for the User, helping them to distinguish different Component Groups in the panel. A single input color will be configured for every Component Group in the `package.yaml` file (see the Design Doc). Therefore, all shades of the color required by the Component Group view must be calculated from this single input color.
https://www.pivotaltracker.com/story/show/181725039
#### Visuals
The following screencast of the `component_group` debug scene shows how all required shades of color are calculated from a single input color. It also shows a new "dimmed" display mode of the Component Group. The debug scene does not support selecting entries in a "dimmed" Component Group, as this is not required by the Design Doc.

The following is a screenshot of the Node Searcher, to demonstrate that it still works correctly:

# Important Notes
- A new type `Params` was added in the `list_view::entry::Entry` trait. This was needed to allow passing FRP information to entries separately for every ListView instance.
- Note: `style_prefix` and `max_width_px` parameters of the `list_view::entry::Entry::new` function may get moved into the new `Params` type in the future. To save time, this was not attempted in this PR, as agreed with @farmaazon.
[ci no changelog needed]
* The List View component was refactored: it allows for hiding the internal selection widget, and exposes information where the widget should be placed. This allows us to create selection widget in component list panel, so it can be animated between component groups and sections.
* Fixed some warnings when checking WASM code.
* Adjusted the style of Component Group View a little, so it better reflects the design doc. Still not ideal, because the list_view has some weird design regarding padding, but I don't want to stuck in some bigger refactoring.
I will add a video in a few minutes.

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

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.
