We need to be able to reference all possible dependencies for ordering
when the configuration is no longer present, which means that absolute
addresses must be used. Since this is only to recreate the proper
ordering for instance destruction, only resources addresses need to be
listed rather than individual instance addresses.

The test fixture did not like having modules when using the generic json
map, so read and compare the states in the final *File datastructure.

Make use of the new Dependencies field in the instance state.

The inter-instance dependencies will be determined from the complete
reference graph, so that absolute addresses can be stored, rather than
just references within a module. The Dependencies are added to the node
in the same manner as state, i.e. via an "attacher" interface and
transformer.  This is because dependencies are calculated from the graph
itself, and not from the config.

Refresh should load any new dependencies found because of configuration
or state changes, but retain any dependencies already in the state.
Orphaned resources would not be in config, but we do not want to lose
the destroy ordering for the later apply.

Updates resulting from orphaned instances should happen after the
deletion of the instances.

The DestroyEdgeTransformer cannot determine ordering from the graph when
the destroyers are from orphaned resources, because there are no
references to resolve. The new stored Dependencies provides what we need
to connect the instances in this case.

We also add the StateDependencies method directly in the
GraphNodeResourceInstance interface, since all instances already
implement this, and we don't need another optional interface to check.

The old code in DestroyEdgeTransformer may no longer be needed in the
long run, but that can be determined separately, since too many of the
tests start with an incomplete state and rely on the Dependencies being
determined from the configuration alone.
