Simplify debug

Hi VS Code PM here 👋

I just tried setting up C++ with VS Code following this tutorial. The flow is actually nice, but here's some feedback on what I think we could improve:

1. C++ should consider contributing to the Editor title area menu, such that a Play button would appear in the Editor Title area. Example how to do this. I am not sure if it would be too noisy to have this on every file C++.
2. You aggressively generate tasks.json and launch.json and you do not provide configurations from memory. Consider providing a dynamic resolveDebugConfiguartion that will provide a launch configuration on the fly. Example
3. If you decide to stick with launch.json generation consider to simplify it. For example stopOnEntry field could be removed.
4. If I have a purple no folder VS Code it is impossible to debug a simple C++ file

I would love if we could improve this experience, since we see in user studies that users want a confirmation that VS Code can do C++, and providing an easy way to run and debug simple C++ files would be great for this.

Let me know if I can help somehow. I am also open to a quick 30 min meeting where we can discuss about the new cool VS Code debug features that C++ could potentially adopt. And you could let us know what are your biggest asks from the VS Code debugger.

fyi @WardenGnaw @weinand

Inizia con il tutorial di configurazione C++ e confronta il flusso attuale di tasks.json e launch.json con gli esempi collegati di vscode-mock-debug package.json e src/activateMockDebug.ts. Per prima cosa, concorda quale delle quattro migliorie proposte rientra nell’ambito; il lavoro sarà completo quando sarà realizzata una semplificazione chiaramente definita e testata del flusso di debugging selezionato, incluso il caso senza cartella se scelto.
