Reverts: flutter/engine#51921
Initiated by: zanderso
Reason for reverting: This Dart roll is blocking the roll of the engine to the framework. Unblocking the rolls depends on addressing https://github.com/flutter/flutter/issues/146164.
Original PR Author: jason-simmons

This change reverts the following previous change:
The Dart SDK is now only building an AOT snapshot for the frontend server (see https://dart-review.googlesource.com/c/sdk/+/359100)
Instead, this PR copies the frontend server from the Dart SDK (whether prebuilt or not) into the location expected by internal engine tests and artifact construction. This PR also consolidates the three GN templates that invoked the frontend server down to one.

The change
https://dart-review.googlesource.com/c/sdk/+/323000 added a dependency on dart2wasm to the frontend_server package.
Flutter engine has all dependencies in its source checkout, and paths to their locations hardcoded in the dependency_ovedrrides of flutter_frontend_server's pubspec.yaml.
Add the dart2wasm package location to pubspec.yaml. Add the transitive dependency wasm_builder package lcoation to pubspec.yaml.
Update: Blocked on https://github.com/flutter/engine/pull/44912 landing,
and merging into google3.

Partial work towards https://github.com/flutter/flutter/issues/112498.
_**tl;dr**: In Impeller's backend we intend to _always_ dither
gradients, and never allow any changes long-term (i.e., write your own
shader if you want different behavior) with the assumption that dithered
gradients look better most of the time, and don't typically hurt
elsewhere._
Note that, at the time of this writing, I couldn't find a single case of
this being set explicitly to `true` inside Google, and there are between
[100 and 200 publicly accessible on
GitHub](https://github.com/search?q=%22Paint.enableDithering%22+language%3ADart&type=code&l=Dart),
of which virtually all are setting it explicitly to `true`.
There are some (valid) concerns this would cause a lot of golden-file
image diffs, so I'm going to seek explicit approval from the Google
testing team as well as someone from the framework team before landing
this commit.
The CL in [0] added package:ffi as dependency to package:compiler. Since
flutter_frontend_server needs all dependencies as path dependencies, we
need to add package:ffi there via path.

The charcode package has been removed from the Dart SDK source
checkout, and the Flutter engine packages that list it in
their pubspecs do not depend on it directly or indirectly.
Remove it from their pubspecs, so they do not break when
the package disappears from the engine source checkout.
