Delegate the queuing of cleared references to managed code.

Previously, the garbage collector would pass each cleared reference to
the heap worker thread for queuing.  The heap worker thread would then
perform a callback into managed code for each cleared reference which
assigned the reference to its reference queue.

With this change, the garbage collector instead links together all of
the cleared references and calls back into managed code exactly once
to hand off the references for processing.  This change makes the heap
worker thread and its data structures obsolete.
