[DevTools][Timeline Profiler] Component Stacks Backend (#24776)
This PR adds a component stack field to the `schedule-state-update` event. The algorithm is as follows: * During profiling, whenever a state update happens collect the parents of the fiber that caused the state update and store it in a map * After profiling finishes, post process the `schedule-state-update` event and using the parent fibers, generate the component stack by using`describeFiber`, a function that uses error throwing to get the location of the component by calling the component without props. --- Co-authored-by: Blake Friedman <blake.friedman@gmail.com>
