[vscode] Implement full Workspace Trust behavior #12318
Description
Feature Description:
VS Code has support for Workspace Trust to let the user decide whether a specific folder/workspace is trusted and therefore extensions that need to work with the code inside it are allowed to do so. If a workspace is not trusted, it will run in restricted mode, disabling any extensions that do not support restricted mode.
User point of view: https://code.visualstudio.com/docs/editor/workspace-trust
Extension point of view: https://code.visualstudio.com/api/extension-guides/workspace-trust
A first implementation of this API was done in [x] where the goal was to implement the extension API to avoid crashing extensions that use it and to have a preference for it. However, the actual behavior of the Restricted Mode and it's effect on the extension was not was not implemented. However, it does affect quite a lot of areas:
- Tasks
- Debugging
- Workspace settings
- Extensions
- Custom UI
The goal of this task is to bring the full Workspace Trust behavior of VS Code into Theia.
