Support horizontal and vertical Aperture Offset on camera

[mdubrois]

Describe the feature you'd like
The horizontal and verticalApertureOffset on the Camera are not yet supported via Hydra or Kick.
See the test below, from 1001 to 1010 the horizontal verticalApertureOffset are animated.
The cube should stick the left border of the render view at the frame 1010.

Describe the solution you'd like
I would like to see the render match the viewport

Describe alternatives you've considered
There is no alternative

Additional context
