This PR adds the ability to do `deriving ReflBEq, LawfulBEq`. Both classes have to listed in the `deriving` clause. For `ReflBEq`, a simple `simp`-based proof is used. For `LawfulBEq`, a dedicated, syntax-directed tactic is used that should work for derived `BEq` instances. This is meant to work with `deriving BEq` (but you can try to use it on hand-rolled `@[methods_specs] instance : BEq…` instances). Does not support mutual or nested inductives.
