    Reland "[platform] Implement TaskRunners in the DefaultPlatform" · 8a1bafaf

    There was a data race in the access of the foreground_task_runner_map_.
    I protect each access to foreground_task_runner_map_ with a lock now.
    
    Original change's description:
    > [platform] Implement TaskRunners in the DefaultPlatform
    >
    > This CL implements the TaskRunners in the DefaultPlatform which has been
    > added recently to the platform API. In addition I changed how task
    > posting works on the DefaultPlatform.
    >
    > With this implementation the DefaultPlatform keeps one
    > DefaultForegroundTaskRunner per isolate, plus one
    > DefaultBackgroundTaskRunner. The DefaultPlatform owns these TaskRunners
    > with a shared_ptr, which is also shared with any caller of
    > GetForegroundTaskRunner or GetBackgroundTaskrunner.
    >
    > This CL moves the task management from the DefaultPlatform to the
    > TaskRunners.  The DefaultForegroundTaskRunner owns and manages the the
    > task queue, the delayed task  queue, and the idle task queue. The
    > DefaultBackgroundTaskRunner owns the WorkerThread pool and the
    > background task queue.
    >
    > In addition changed many Task* to std::unique_ptr<Task> to document task
    > ownership.
