    [offthread] Introduce "transfer" handles for off thread · c948f08f
    Leszek Swirski authored
    Introduce an OffThreadTransferHandle (and OffThreadTransferMaybeHandle),
    which points to a piece of storage known to (and owned by) the
    OffThreadIsolate. On Publish, the OffThreadIsolate converts this storage
    stub from a raw pointer to an off-thread object into a main-thread
    Handle.
    
    This allows users of an OffThreadIsolate to not have to worry (as much)
    about the dance of saving raw object pointers before off-thread finishes
    and converting those to Handles before it off-thread isolate is
    published.
