In #2884, Terraform would hang on graphs with an orphaned resource
depended on an orphaned module.
This is because orphan module nodes (which are dependable) were getting
expanded (replaced) with GraphNodeBasicSubgraph nodes (which are _not_
dependable).
The old `graph.Replace()` code resulted in GraphNodeBasicSubgraph being
entered into the lookaside table, even though it is not dependable.
This resulted in an untraversable edge in the graph, so the graph would
hang and wait forever.
Now, we remove entries from the lookaside table when a dependable node
is being replaced with a non-dependable node. This means we lose an
edge, but we can move forward. It's ~probably~ never correct to be
replacing depenable nodes with non-dependable ones, but this tweak
seemed preferable to tossing a panic in there.
We weren't marking skipped nodes as failing, so any
grandchild-and-deeper dependencies would still evaluate.
For example:
A -> B -> C -> D
If B failed, C would be skipped, but D would still be evaluated.
This fixes the behavior so C, D, and any further descendents will all be
skipped when B fails.
Addresses crashing aspect of #2955 and likely a lot of other confusing
failure modes.

This commit exports the `arn` as well as the `id`, since IAM
roles require the full resource name rather than just the table
name. I'd even be in favor or having `arn` as the `id` since the
<region, tablename> pair is the uniqueness constraint, but this
will keep backwards compatibility:
