This patch avoids requiring the main thread to create PBackground instances by instead using a background starter TaskQueue, and sending messages from a PBackgroundStarter actor hosted on that thread to the target background thread directly. On the background thread, the relevant metadata is already registered and present in the BackgroundStarterParent actor allowing the main thread in both processes to be bypassed completely. Various tasks remain bound to the main thread, such as PBackground cleanup and async steps involved in PBackground creation. This patch also unifies the in-process and cross-process PBackground codepaths, allowing in-process PBackground creation to bypass the main thread as well, and removing the need for a main thread event target from GetOrCreateForCurrentThread().
