Add functionality to run provider version upgrade tests

We need to implement a method to automatically catch errors caused by provider version upgrade.

Based on our current test setup, we don't have a good way to detect upgrade errors. Such error occurs when resource was created with an earlier version of providers and then upgraded to the latest version, e.g., #12917, #12422

Note: We have the release_diff stuff kicking around from the tpgtools migration plan that could likely get reused here.

We had an issue in a DCL->MMv1 migration PR for orgpolicy_policy where the resource would "disappear" on upgrade because the expected ID format changed. We believe this would have been caught by a RELEASE_DIFF test. GoogleCloudPlatform/magic-modules#10759

For some reason the release diff test didn't catch it but a manual test using developer overrides did.
