Restart Frame shown on async part of stacktrace

#89393 testing on Windows.

Restart Frame is shown on past parts of the stacktrace. It doesn't work:

cc @isidorn @weinand. Mentioned there, I think the most reliably way would be to have an annotation from the debug adapter indicating whether or not each stack frame can be restarted.

[isidorn]

If we do not introduce a new annotation for this the best I could do from the UX side is to not show Restart Frame action on deemphasize stack frames.
What do you think about that approach?

[connor4312]

I think an annotation would be better. I'm not sure using deemphasis alone as the boundary is totally correct for js-debug, and may not work for other debuggers.

@connor4312 this can be closed, right?

[isidorn]

I tried this out and was working fine for me. Thus closing this and @connor4312 can reopen if needed
