Revert "Move most of the code from u/b/kernel_worker.dart to p/frontend_server"

This reverts commit 659fdae898d4c1095bfb9c76617f3c34686a82a7.

Reason for revert: Broke the HHH bots.

The fix according to zra@ should be:

"The new dependencies should be added as dependency overrides to flutter_frontend_server's pubspec.yaml: https://github.com/flutter/engine/blob/master/flutter_frontend_server/pubspec.yaml"

Original change's description:
> Move most of the code from u/b/kernel_worker.dart to p/frontend_server
>
> This should allow us to import the code in cases when we want to
> implement the Bazel worker loop ourselves. This opens some possibilities
> of extra optimizations for internal use cases.
>
> I'm leaving some of the code (e.g., `main`) in the old location, so that
> we do not break anything that depends on it.
>
> The only thing that I've done is to pass the input-digest map to
> `computeKernel` instead of using `Input` objects directly, this way
> we can avoid the dependency on `package:bazel_worker` from
> `frontend_server`. So now, if we're using the worker loop, the map will
> be computed by `kernel_worker.dart` (in non-worker mode, we rely on
> the default empty map).

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
