url_launcher plugin broken

[provokateurin]

This PR breaks the go-flutter url_launcher plugin implementation completely.

What should we do?
I/We cannot keep up with the pace at which google is pushing modification. Sadly this one is a breaking one.
I haven't looked at the how native plugin implementation works, it might actually be easier than the current method-channel-based one as it seems to call native code directly from dart without calling the embedder.
TODO: add dart ffi native plugin support.

Edit 13/05/2022
I've side track a bit.
The issue was not about dart ffi, but about the modification of channel names.

# before
"plugins.flutter.io/url_launcher",
# after
"plugins.flutter.io/url_launcher_macos",
"plugins.flutter.io/url_launcher_windows",
"plugins.flutter.io/url_launcher_linux",

fixed in go-flutter-desktop/plugins#74

TBH except for packaging to mac and linux the official embedder has become superior :( I already talked with @GeertJohan about maybe extracting the packaging code and making a separate tool for just packaging flutter desktop apps.

I'm not supporting adding new feature/refactoring parts of the go-flutter project.
The core functionality of go-flutter project still works, even though many features have been added to Flutter. I'm happy with the current state. For a non-official embedder, it's sufficient.

Having the official embedder become superior was just a question of time.

Our software is good. The use of golang is an excellent way of writing plugins.
But it only is interesting for a small set of users. For the majority, the official embedder will always be better.

FYI this is a Flutter bug: flutter/flutter#103660

Changes like the one referenced above were supposed to have no effect on custom embeddings like this one.
