multi debug console feature is not aligned with integrated and external terminals

[weinand]

• run cluster sample

Observe: every process gets its own debug console

• set "console" attribute to "integrated terminal"
• run cluster sample again

Observe: all processes run in a single terminal

We should consider to represent the multi debug console feature as a new console type "multi console".

Currently the console field is contributed by the node debug adapter, vscode is not aware of this.
So I would suggest that this one we solve on the node debug side piggy backing on #62419
So after we add that flag the node debug adapter would turn on that flag if the console attribute is not internalConsole.

After discussion we have decided to solve this by tackling it from the cluster sample perspective.
In a case that autoAttachToChildProcess is enabled the node debug would automatically switch the console option to use the integrated terminal

Seperate from this we will tackle #62419 once we get more user feedback
