Camera2: Clean up corner case error handling

- If a session is closed, and a new session is created immediately
afterwards, but then fails to be configured, the first session sees an
onUnconfigured call which it wasn't expecting, and throws an
exception on an internal thread, leading to app death.
Add a guard against this case.

- If the lower levels skip a frame (illegal per design), be slightly more
robust to that by accepting any successful result as the latest completed
frame, instead of just incrementing the completed frame count. This will
lead to missing results, but should allow shutdown, etc, to complete
cleanly.

- Convert TIMED_OUT error codes to CAMERA_ERROR CameraAccessExceptions.
This is a common error code returned by waitUntilIdle.

Also, improve debug logging to log a session ID with verbose logging,
and add a few verbose logs.
