Simon Zünd a55ecfaf7f Reland "[debug] Immediately step-in for 'stack check triggered' debug breaks" 
This is a reland of commit 3297ccca23

This is a straight-up reland of the original CL. The failing test
was flaky and removed with https://crrev.com/c/3868727. We replaced
the test with a proper DevTools e2e test: https://crrev.com/c/3867522

Original change's description:
> [debug] Immediately step-in for 'stack check triggered' debug breaks
>
> This CL changes debug breaks that are triggered via interrupts (i.e.
> via stack check). One client of this behavior is the `Debugger.pause`
> CDP method.
>
> The problem is that when we pause so early, the JSFunction didn't have
> time yet to create and push it's context. This requires special
> handling in the ScopeIterator and makes an upcoming change unnecessary
> complex.
>
> Another (minor) problem is that local debug-evaluate can't change
> context-allocated local variables (see changed regression bug). Since
> the context is not yet created and pushed, variables are written to
> the DebugEvaluateContext that goes away after the evaluation.
>
> The solution is to mirror what `BreakOnNextFunction` does. Instead
> of staying paused in the middle of the function entry, we trigger
> a "step in" and pause at the first valid breakable position instead.
> This ensures that the function context is already created and pushed.
>
> Note that we do this only in case for JSFunctions. In all other cases
> we keep the existing behavior and stay paused in the entry.
