This changes the CFE expectation test suites to use unsound null safety as default to avoid passing --enable-experiments=no-non-nullable to opt out old test folders. This change removes most test folders from the 'strong' tester, since this now only supports sound null safety, which requires all libraries to be opted in. Instead, the 'weak' tester now runs all test folders. Additionally the 'outline' tester is changed to use unsound null safety so that it call be used on all test folders. The 'fast_strong' tester is removed since it should just be run locally and it can be run by passing an option to the other testers. References to non-existing 'shaker' folder has been removed from testing.json.
