Camera: Add lastCompletedFrameNumber in CaptureResultExtras

The new fields in CaptureResultExtras notify the application the last
completed frame numbers. A frame number is completed if:
- All buffers are returned
- Final capture result is returned, or CAPTURE_ERROR is called,
- For buffers that are cancelled, all notifyError() is called.

This makes sure client doesn't ignore BUFFER_ERROR after capture
result metadata callback.

Public API and NDK logic are fixed. VNDK is yet to be done.

Test: Camera CTS
