Reverts: flutter/engine#54557 Initiated by: zanderso Reason for reverting: Failing on framework tests on the roll https://ci.chromium.org/ui/p/flutter/builders/try/Mac_arm64%20run_debug_test_macos/9841/overview Original PR Author: cbracken Reviewed By: {jmagman} This change reverts the following previous change: This is a refactoring with no semantic changes. This refactors the macOS framework creation code to be more readable, and extracts it to `sky_utils.py`. While I was pulling this out, also generalised the code to not hardcode `FlutterMacOS.framework` in case we one day manage to generate the iOS and macOS frameworks with the same name. This is a reland of flutter/engine#54546 (reverted in flutter/engine#54549), the original was reverted in order to revert flutter/engine#54543 (reverted in flutter/engine#54550), which was reverted because it failed to preserve symlinks while zipping the macOS framework. That patch has been relanded with a fix in flutter/engine#54555. This patch has been rebased to tip-of-tree for attempt two.

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.
