pgsql: Use dlist/dclist instead of PROC_QUEUE / SHM_QUEUE for heavyweig

Use dlist/dclist instead of PROC_QUEUE / SHM_QUEUE for heavyweight locks

Part of a series to remove SHM_QUEUE. ilist.h style lists are more widely used
and have an easier to use interface.

As PROC_QUEUE is now unused, remove it.
