Adds Timeline events for every Widget built.

For details on how to use Timeline events in the Dart Observatory to optimize your app, see https://fuchsia.googlesource.com/sysui/+/master/docs/performance.md

See also debugProfilePaintsEnabled, which does something similar but for painting, and debugPrintRebuildDirtyWidgets, which does something similar but reporting the builds to the console.
