cts: Add test to enforce max aspect ratios match.

Bug: 16737746

Update CTS with backward compatibility requirements for Camera2 API
to ensure:
 - The largest preview and jpeg outputs available on the device
   have the same aspect ratio as the camera sensor.
 - These sizes are appropriately reported in
   getSupportedPreviewSizes() and getSupportedPictureSizes().
