Before this change, the Flutter adapter always sent "supportsRestartRequest: true" to the DAP client. This told the DAP client if the user clicks the "Restart" button on the debug toolbar that we (the DAP server) will handle the restart (allowing us to Hot Restart instead of a slower termination and restart of the entire debug session). However, Profile/Release mode do not support Hot Restart, so this would result in an error "Hot Restart failed". This change no longer sets `supportsRestartRequest: true` at startup, but instead waits for the `app.start` event, and sends the value of its `supportsRestart` field (an existing field that was already available in the `app.start` event). This results in Hot Restart being available for debug builds, but the DAP client/IDE performing a full debug session restart for other modes. Fixes Dart-Code/Dart-Code#4281.
