[DevTools] Double click a Suspense Rect to jump to its position in the timeline (#34642)

When you double click it will hide or show by jumping to the selected
index or one step before the selected.

Let's you go from a suspense boundary into the timeline to find its
position. I also highlight the step in the timeline when you hover the
rect.

This only works if it's in the selected root but all of those should be
merged into one single timeline.

One thing that's weird about the SuspenseNodes now is that they
sometimes gets deleted but not always when they're resupended. Nested
ones maybe? This means that if you double click to hide it, you can't
double click again to show it. This seems like an unrelated bug that we
should fix.

We could potentially repurpose the existing "Suspend" button in the
toolbar to do this too, or maybe add another icon there.
