config/hcl2shim: shims from flatmap to cty and vice-versa
These particular shims will have a pretty limited lifetime in mainline Terraform code (primarily to stub out the new expression evaluator against the old state structs until the new format is implemented) but will live on for some time in state migration and provider plugin compatibility shims.
