Resolve "ENG: Full Hero Carousel"

This MR closes Full Hero Carousel #1306 (closed)

Here is a preview:

In the review app, the component is hidden, as we just want to have it ready for the nextAB test.

Meanwhile, we would like to have the refined copy for the slides of the carousel @KristinaWeis.

About the design, we would like your approval @ctsang-ext @jhalloran
