[analysis_server] Pre-compile server for integration tests By default the integration tests spawn the server using the snapshot from the active SDK. If you forget to recompile the SDK when running the integration tests, you may get inaccurate results. One option is to set the `TEST_SERVER_SNAPSHOT` env variable to `"false"` which will run the tests from source, however using the "Run All Tests" command in VS Code will result in a lot of timeouts because tests run concurrently and each one will cause a compilation. This change instead creates a new VS Code task that will compile the server to a temporary file in `.dart_tool`, and creates a launch configuration that triggers this task (via `preLaunchTask`) when running integration tests. This supports both running all tests (with the "Run All Tests" command) or running individual integration test files, with just a single up-front compilation.

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).
Dart is free and open source.
