Reland "Add support for Dart Development Service (DDS) in Flutter Tools (#61276)" (#62147)
This reverts commit adc9dde3ba.

- Fixed issue where `FallbackDiscovery` would hold on to a `VmService` when launching on iOS devices, causing DDS to fail to start
- Fixed `flutter drive` case where DDS is already running in another flutter_tools instance
