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
