Camera API 2, Device 2/3: Implement idle and shutter callbacks

- Update callback Binder interface
- Rename frameId to be requestId to be consistent and disambiguate
  from frameNumber.
- Implement shutter callback from HAL2/3 notify()
  - Add in-flight tracking to HAL2
  - Add requestId to in-flight tracking
  - Report requestId from shutter callback
- Implement idle callback from HAL3 process_capture_result
  - Add new idle tracker thread
  - Update all idle waiting to use the tracker
  - Add reporting from request thread, all streams to tracker
  - Remove existing idle waiting infrastructure
