Clipping in the Scroll Area (reverting a revert) (#3420)
[ci no changelog needed]

This is fixed copy of already reviewed #3384

[Task link](https://www.pivotaltracker.com/story/show/181413200)

This PR implements content clipping for the ScrollArea component.

List of changes:
- Implemented `InstanceWithAttachedLayer` abstraction that allows creating additional sublayers for our components. In the future, this abstraction can be used for text rendering as well (right now text rendering requires additional hardcoded layers).
- Fixed `complex-shape-system` demo scene by removing `node_searcher_mask` layer.
- Fixed `SublayersModel::remove` - it was not clearing the `layer_placement` hashmap.
- Implemented disabling the wheel scrolling in `Navigator`, and refactored it to reduce the number of functions arguments by introducing a `NavigatorSettings` struct.

# Important Notes
- `InstanceWithAttachedLayer` is implemented in such a way that it allows an extension in the future - namely to use it to simplify text rendering. The implementation might be simplified though.
