* Add @slow decorator to run tests on `main` This adds the infrastructure discussed in https://discuss.tvm.apache.org/t/rfc-ci-skip-slow-tests-on-prs/11910, but without affecting any tests. As we investigate reasons behind [slow tests](https://gist.github.com/driazati/e009f09ff44c6bc91c4d95a8e17fd6f1) in CI, this decorator will allow us to move these to run only on `main` and not PRs after checking with all concerned parties. * cleanup Co-authored-by: driazati <driazati@users.noreply.github.com>
