camera2: Add capture sequences and capture failures

- CaptureResult#getRequest is used to tie a result to a request (for convenience)
- Add new CaptureFailure class to describe capture failure
- Results/frame numbers also return frame numbers, sequence ids
- Captures now all return the sequence id
- A sequence id onComplete is available in the CaptureListener
