markers: better sync between editor and problems-view

[vince-fugnitto]

Description

At the moment, there is no sync between the active editor and the problems-view meaning that problems are not revealed in the tree based on the editor.

There are two main use-cases not handled:

• switching/opening an editor does not reveal it's markers in the problems-view
• if markers are collapsed in the problems-view, the active editor's node is not expanded

Both use-cases are successfully handled by vscode:

In order to sync the markers with the activeEditor. We will need to couple the Editor with Markers, imo. Is there any other way/suggestion for fixing this issue without coupling the two?

You can rely on NavigatableWidget. EditorWidget implements it.
