Martin Atkins 7cab34815a lang/eval: PlanningOracle.AwaitResourceInstancesCompletion ...

This is a building block for use by a planning engine implemented elsewhere
in OpenTofu so that it can be notified (by the completion of a call to the
function) when all resource instances that use a particular provider
instance or ephemeral resource instance have completed their plan-time
evaluation work.

Existing methods of PlanningOracle already expose sets of addresses to
wait for, but this method is separate from those because the planning
engine also needs the dependency information as data to know when an
ephemeral resource instance might need to be left open beyond the part of
the planning process driven by lang/eval in order to plan the delete
actions for any "orphan" resource instances that are in the prior state
but no longer declared in the configuration.
