…#193459)

## Description

When `no-launch-chrome` is passed in platform args (e.g. during `flutter
drive -d chrome`, where WebDriver launches the browser instead of
Flutter), `ChromiumDevice.startApp` does not launch Chrome. As a result,
`ChromiumLauncher.connectedInstance` never completes.

This caused `flutter drive -d chrome` to hang:
1. `ResidentWebRunner.attach` awaited
`ChromiumLauncher.connectedInstance` before signaling that the app
started. Because `DriveCommand` awaits `driverService.start()` before
calling `startTest()`, WebDriver was never started and the command hung
indefinitely.
2. Even if `attach` was bypassed, DWDS defaulted to Chrome-based
debugging for `ChromiumDevice`, whose connection provider also awaited
`connectedInstance`.

This PR fixes both issues by:
- Only waiting on `connectedInstance` in `attach()` if the tool actually
launched Chromium.
- Switching DWDS to the WebSocket debug connection when
`no-launch-chrome` is set, matching the `web-server` device behavior.

Fixes flutter#192091
