This change offloads all Dart actions during the build to RBE using the new rewrapper_dart.py script that understands all the different command line invocations of Dart programs and translates it into the appropriate rewrapper invocation, with a full list of input and output files and no absolute paths. The dart actions are all considered to be expensive RBE compilation steps that may be much slower on RBE than locally due to the low parallelism of the build during these stages and the comperatively slower bots in the RBE pools. The build uses the racing strategy by default for these compilations, such that cache hits are still used if available, and otherwise a local build is transparently used if it happens to be faster. The bots will use the remote strategy by default unlike developers, such that the rewrapper_dart.py script does not fail. rewrapper_dart.py contains a tiny dart import proprocessor written in python and a big argument parser that understands every command invoked during the build and the semantic meaning of every option. The absolute paths used during the Dart SDK build is not solved in this changelist, which just works around them initially, but these will be fixed in follow up changes with the appropriate teams now that this change proves they are not needed.

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).
