This will allow users who are implementing their own deferred loading mechanism to batch all the loads for a specific library. Today in order to do batching users have to gather the URIs passed to the `dartDeferedLibraryLoader` hook in a list and schedule (e.g. via setTimeout) a load for some future task. The need to schedule a task has been shown to cause delays in IPL. But loading each part file individually can also be very expensive. So this allows for a compromise where bundling can be done synchronously per loaded library. Adds ~8kB to unminified main files and ~2.5kB to minified main files.
