[DevTools] Handle reordered contexts in Profiler #30887

While looking at the Context tracking implementation for other reasons I noticed this bug.

Originally it wasn't allowed to have conditional useContext(context) (although we did because it's technically possible). With use(context) it is officially allowed to be conditional as long as it is within a Hook/Component and not within a try/catch.

This means that this loop comparing previous and next contexts need to consider that the Context objects might not line up and so it's possibly comparing apples to oranges. We already bailed if one was longer than the other.

If the order of contexts changes later in the component that means something else must have already changed earlier so the reason for the rerender isn't the context so we can just return false in that case.
