This PR updates the gradle build file for the android_embedding_bundle cipd package to fetch license information about the dependencies listed under `tools/androidx/files.json`. The README file for the android_embedding_bundle now explains how to fetch the license information and make sure it's correct in the cipd package. This PR also pulls a new version of android_embedding_dependencies that includes a `LICENSE` file. It turns out that Flutter does not re-ship anything from the embedding bundle to Flutter end-users. These dependencies are only used to create a classpath against which we build the Android embedder and in-tree tests. I've updated docs/comments to clarify that since I was initially confused about how these were used. I'm not adding a test that compares the license info fetched from maven against a checked-in golden, yet. Still thinking about the most effective way to do that in combination with the steps in the README.
Flutter Engine
Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.
