Adapter_oM: Command for controlling visibility of external software window during CRUD

#### Description:

Additional Command to control if you want the UI of the adapter to be shown or not. Many action can run quicker when the UI window is closed, as it can make the software skip refreshing viewports and similar.

Thinking of adding it in the base Adapter_oM to centralise.

SOmthing like

```

public class UiWindowControl : IExecuteCOmmand
{
public virtual bool IsVisible {get;set;} = true;
}

```

More than happy for a better name for it!!

Start by reviewing the proposed base Adapter_oM location and the IExecuteCOmmand example in the issue. Clarify the command name, visibility behavior, and how it should apply during CRUD operations; done means the project has an agreed API and implementation for controlling the external software UI.
