[dds/dap] Fix flaky DAP test

There were two issues here:

1. During shutdown, when trying to unpause and resume all threads we could get "Service has Disappeared" responses if the app was already shutting down. These need ignoring. This is fixed with `_withErrorHandling` in preventBreakingAndResume.

2. The test teardown would always try to send a terminate request even if the test had already sent it, which could result in a second terminate request not being responded to (because the app shutdown before it could respond, because it had already had a terminate request). This is fixed by the teardown code only sending terminate() if it hadn't already been sent.

Fixes https://github.com/dart-lang/sdk/issues/51970.

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).
