Pass --web-define through to web runner when using --machine mode (flutter#183228)

This passes `--web-define`s through to the machine daemon used when
`flutter run` is invoked with `--machine` (which is the case for IDEs).

Fixes flutter#183170
Fixes Dart-Code/Dart-Code#5942

**Note**: The Flutter team is currently trialing the use of [Gemini Code
Assist for
GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code).
Comments from the `gemini-code-assist` bot should not be taken as
authoritative feedback from the Flutter team. If you find its comments
useful you can update your code accordingly, but if you are unsure or
disagree with the feedback, please feel free to wait for a Flutter team
member's review for guidance on which automated comments should be
addressed.
