Use Service ID zones where beneficial

The APIs for managing Service ID zones have been released in [`package:vm_service 14.3.0`](https://pub.dev/packages/vm_service/versions/14.3.0). These APIs can be used to free object IDs when they are no longer needed, to ensure that objects associated with those IDs are not retained for longer than necessary. I believe that [using Service ID zones in DAP](https://github.com/dart-lang/sdk/issues/56794) will have the biggest impact on the memory footprint of debugging, but please check if DevTools can benefit from these APIs in any way.
