In the Flutter engine, we plan to expand and start using Dart actions to
rely more on the GN build system, and less on home-grown (Python/Bash)
tooling. To that end, we'll start generating dart_snapshot and dart_test
rules that are invokved the same way locally (via `et`) and on CI, with
a goal of making all of our tests programatically discoverable.
We need the `metadata` field (a standard GN field) in order to tag our
outputs (i.e. `metadata = { action_type = ['dart_executable'] }`);
see https://gn.googlesource.com/gn/+/main/docs/reference.md#var_metadata.

This directory was taken from a snapshot of flutter/engine/src/build/.
The snapshot was taken with a recursive copy cp -R of the directory from
the flutter repository.
The contents has now diverged significantly from Flutter, and is maintained independently by the Dart team. It is used to support the GN build system.
