fixes #20653, which was reported for opensearch domains, but also fixes this issue for all other resources that allowed this removal policy but did not actually support it.

previously, the behavior was a successful synth and deploy, and cloudformation ignores the snapshot removal policy if it is not supported by the resource. because of this, i believe that i have to add this fix behind a feature flag to avoid breaking customers.

without the feature flag, the best we can do is add a warning to the stack notifying customers that the snapshot policy is useless.

Let's add a warning for this that isn't under a feature flag so that customers who don't opt in to the feature flag will still get alerted, but not have an error thrown.
