Don't show skip file action for programs

[jrieken]

re #19096

• Launch two debuggees
• right click on one of the app nodes in the tree
• 🐛 the menu shows the skip file entry

@isidorn I don't think I can control this?

"debug/callstack/context": [{
  "command": "extension.node-debug2.toggleSkippingFile",
  "group": "navigation"
}]

[isidorn]

@roblourens on my end I could only enable this context menu contributions on the stack frame elemnts but that feels a bit hackish. Extensions should be able to contribute some other actions to program / thread, so in a perfect world we would be able to specify somehow for what elements in the context menu should they be shown.
Having 3 different contribution points also feels a bit ugly, one for stack frame, one for thread, one for program

@jrieken suggestions are welcome

We could add a 'when' clause context?

[isidorn]

@roblourens I think the when clause was designed with something else in mind, like when in debug. It does not feel natural to me to add a context when 'stackFrameSelected'

[roblourens]

Most of them are like 'thingHasFocus' or 'thingIsVisible' but what we want seems analogous to "resourceLangId == markdown" which is how you can show context menu items only on certain types of files in the explorer. Like I'm imagining "callStackItemType = stackFrame".

That might be too specific though. Besides that, 3 different contribution points might be ok. Maybe @jrieken has a better idea.

@roblourens we can look into adding something like that in February

[roblourens]

Is this realistic or should we close it?

[isidorn]

Sure we can do this but I do not see the end for this in the immediate future since nobody else complained.
