Given a definition `foo`, they were previously called `foo._unfold` until 4.7.0. We tried to rename them to `foo.def`, but it created too many issues in the Mathlib repo. We decided to rename it again to `foo.eq_def`. The new name is also consistent with the `eq_<idx>` theorems generated for different "cases". That is, `foo.eq_def` is the equality theorem for the whole definition, and `foo.eq_<idx>` is the equality theorem for case `<idx>`. cc @semorrison
