Ben Konyi ab6780d13e [dds][dart_runtime_service] Dynamically allocate ChromeDriver ports and fix SSE test flakiness
This change addresses flakiness in SSE tests caused by port conflicts
and race conditions during connection teardown.

Key changes:
- Dynamically allocates ChromeDriver ports in `sse_smoke_test.dart` and `sse_client_test.dart` instead of using a hardcoded port (4444). This avoids conflicts when tests run in parallel on CI bots.
- Adds support for locating ChromeDriver via the `CHROMEDRIVER_PATH` environment variable in both test suites.
- Updates `sse_smoke_driver.dart` to introduce a brief delay before closing connections. This ensures the client-side SseClient has sufficient time to flush its final POST request to the server, avoiding "Bad state: No element" errors.
- Modifies `test_helper.dart` to filter out `--mark_main_isolate_as_system_isolate` from arguments forwarded to spawned testee processes. This is necessary under modern `dart test` runners to ensure processes pause at start as expected.

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).
