[infra] Make deflaking optional in test.dart

This adds a "--deflake" flag to test.dart. Deflaking will only run if
that flag is set.

Deflaking is time consuming and delays the information that users want
to see when most of the time they know that the result is not caused by

A typical session may look like this:
* Run test.dart with a broad test selector without deflaking.
* Re-run test.dart with a narrow test selector for suspected flakes with
  "--deflake". This second step is optional.

Additionally, a new "--report-flakes" flag is added that can be
used to report test failures for tests known to be flaky.

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 has 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).
