Reduce service isolate startup time from ~80ms to ~30ms

- Get access to dart:io internal signal listening function using API instead of mirrors.

- Service isolate can start with service deactivated.
- Load Observatory front end resources only when service activated.
- Do not execute Dart Service code until service is activated.
- Register live isolates when service is activated.

- Startup refactored to allow for future use of script snapshots.
