Stacked on #30979. The problem with the previous approach is that it recursively walked the tree up to propagate the resulting time from recording a layout effect. Instead, we keep a running count of the effect duration on the module scope. Then we reset it when entering a nested Profiler and then we add its elapsed count when we exit the Profiler. This also fixes a bug where we weren't previously including unmount times for some detached trees since they couldn't bubble up to find the profiler.
