Camera: Pass system health metrics to ServiceProxy

- Measure session statistics:
  - Camera open, close, and session creation latency
  - Session information such as camera id, is_ndk, operating mode,
    and reconfiguration count.
- Measure stream statistics:
  - width, height, format, dataspace, usage
  - max buffer count
  - buffer loss count
  - startup latency.

Test: ./out/host/linux-x86/bin/statsd_testdrive 227
Test: Camera CTS, VNDK test
