camera2: validate reprocess request's session

Add a session ID to CaptureResult to indicate the session where
the result comes from. When creating a reprocess capture request
with a capture result, the session ID will be carried over to
the reprocess capture request. Reprocess capture request's session
ID will be used to validate that it matches the session ID when
submitting the reprocess capture request to a session.
