This change moves most of SerialQueue into SerialStorage and factors it to make SerialMap and SerialQueue. SerialMap does not enforce that items are Enqueue'd in monotonically increasing order. This is useful for implement timeline fences because OnCompletion callbacks may be added in an arbitrary order.
