Deprecates `inductive ... :=`, `structure ... :=`, and `class ... :=` in favor of the `... where` variant. Currently this syntax produces a warning, controlled by the `linter.deprecated` option. Breaking change: modifies `Lean.Linter.logLintIf` to use `Lean.Linter.getLinterValue` to determine if a linter value is set. This means that the `linter.all` option now is taken into account when the linter option is not set. Part of #5236
