    [heap] Cache ForegroundTaskRunner in CollectionBarrier

    The API doesn't allow us to invoke GetForegroundTaskRunner() from
    a background thread. We need to cache the task runner in the ctor
    of CollectionBarrier during heap setup.

    We can't create the CollectionBarrier inside Heap's ctor anymore
    because at that point the TaskRunner might not be set up (e.g. Node).

Original commit message:

    [heap] Cache GetForegroundTaskRunner in IncrementalMarkingJob

    Our API doesn't allow us to invoke GetForegroundTaskRunner() from
    a background thread. We need to cache the task runner in the ctor
    of IncrementalMarkingJob during heap setup.

    This is necessary because we may start incremental marking from
    background threads.
