Zach Anderson 7471994270 Revert "[vm/ffi] Add class modifiers" 
This reverts commit 1755f89092.

Reason for revert: This is a breaking change and is blocking the Dart -> Flutter roll. See https://ci.chromium.org/ui/p/flutter/builders/try/Mac%20Unopt/26896/overview.

Original change's description:
> [vm/ffi] Add class modifiers
>
> Adds class modifiers to `dart:ffi`.
>
> Migrates all user-defined subclasses of `Struct`, `Union`, `Opaque`,
> and `AbiSpecificInteger` to be `final class`es.
>
> Does not remove the manual error checking, so some errors will show up
> twice now in language version 3.0. In language version <3.0, only the
> FFI-specific error will show up.
>
> In a follow-up CL, we will try to make the language-errors to show up
> also <3.0 so that we can remove the FFI-specific errors.
>
> Examples of duplicated errors:
> pkg/analyzer/test/src/diagnostics/subtype_of_ffi_class_test.dart
>
> TEST=pkg/analyzer/test/ (for the analyzer)
> TEST=pkg/front_end/testcases/ (for the CFE)
> TEST=test/ffi/ (for the VM)
>
> CoreLibraryReviewExempt: No need for dart2js to review.

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).
