[fixnum] Make Int32 and Int64 final Int32 and Int64 are value types and there is no reason real instances can't be used. The upcoming `Mockito` release adds dummy values using the real `.ZERO` instances. https://github.com/dart-lang/build/pull/4961 Statically disallow sublcasses by marking the leaf classes `final`. This is a breaking change for any code outside this package that extends or implements Int32 or Int64, but this was never an intended use case.
