In the case where a provider has been upgraded, and there are external changes to resources outside of terraform, and -target is being used, and resources which are not targeted require a schema migration; the untargeted resources will not have been migrated and cannot be decoded for the external changes report. Since there is no way to decode the resources which have been excluded via -target, we can only skip over them when inspecting driftedResources. Return warnings for now to indicate that these resources could not be decoded to help indicate that users will need to eventually apply these changes.
