[ffigen] Bumped dart_style to 3.0

[Levi-Lesches]

Was hitting an issue in some of my projects that ffigen: ^16.0.0 depends on dart_style: <3.0.0 which depends on analyzer: <7.0.0, but analyzer 7.0.0 is being used by some other packages, which makes ffigen the bottleneck. This PR fixes that by simply bumping dart_style from ^2.3.7 to ^3.0.0.

The biggest change from dart_style (see the changelog) is the mandatory inclusion of the language version, in order to facilitate the new 3.7 formatter. Luckily, ffigen already passed this parameter voluntarily, so no code change was necessary.

I set the formatter that runs on the generated code to stick to short style for now, since Dart 3.7 that introduces tall style hasn't released on stable yet. In the future, we'd probably want to find a way to read the current project's language version and use that instead.

👍

As soon as Dart 3.7 is out. I'd like to bump all the packages in this repo to 3.7 and reformat the whole repo. (It will mean that package:jni, package:ffi, and package:objective_c for the new Dart & Flutter SDK, but I think that's fine.)

FYI @liamappelbe @HosseinYousefi Us running the formatter from source means we're running whatever version of the formatter we use in FFIgen/JNIgen. Maybe we should consider going back go dart format so that we use the formatter of the SDK our users are using.
