Since we started depending on GLib 2.44, we can be sure this macro is defined (it will be a no-op on compilers that don't support it). For plugins we should just start using `G_DECLARE_FINAL_TYPE` which means we no longer need the macro there, but for most types in base/gst-libs we don't want to break ABI, which means it's better to just keep it like it is (and use the `#ifdef` instead).
