Android: Wait for camera device close before stopping background thread

CameraDevice.close() is async: Camera2 keeps posting internal
callbacks (e.g. onClosed) to the background handler after it returns.
stopAndClose() previously returned immediately, letting the caller
join the background thread before that post arrived, racing thread
teardown against Camera2's own callback delivery.

This patch adds a wait for CameraDevice.onClosed() before returning from
stopAndClose(), so the background thread stops only after Camera2 is
done with it. The wait must not run while rwLock is held, or a queued
callback needing that same lock deadlocks.
