[stable] Migrate from Goma to RBE.

This change is a necessary infrastructure migration that switches
building dart for testing to RBE instead of Goma. The release
artifacts are unchanged as RBE must not be used for official
releases and only affects the commit queue and post-submit testing.

The anthology of RBE commits to main since the 3.3.0 branch point is
cherry-picked in their entirety without merge conflicts to put the
stable branch in the same supported state as main.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

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).
