[analysis_server] When running server from source in integration tests, pre-compile server When working on the analysis server, you can set the `TEST_SERVER_SNAPSHOT` env var to `false` to spawn the server from source (`bin/server.dart`) instead of running the snapshot, which allows easily running the integration tests (which spawn the server in a separate process) from the IDE without having to run (and wait for) builds. However running from source like this can be quite slow because every test that spawns the server results in it being compiled on-the-fly. This change instead uses `dart compile` to compile the server from source to a temp file the first time we return the path, and then subsequently returns the same path. On my Windows PC, this reduces the time to run the integration tests (with the env variable set) from 17min to 2min.

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.
