Terraformimportforaws_route_tableshouldnotimportdynamicroutes

This issue was originally opened by as hashicorp/terraform#18418. It was migrated here as a result of the provider split. The original body of the issue is below.

When running a terraform import to import a routing table, dynamic routes that get propagated via a virtual private gateway are also imported.

This is problematic as those routes will not have an equivalent resource in terraform. As a result, terraform will try to delete these routes on subsequent runs.
