[A11y]: InoCrousel & InoCarouselSlide

[Sl1nd]

Currently InoCarousel is not accessible at all. Things that must be implemented/missing:

1. "left" and "right" InoIconButtons do not provide 'aria-labels'
2. <div "ino-carousel__container" should be refactored to '
   ' Element
3. <div "ino-carousel__container" should provide a aria-roledescription with value "carousel"
4. <div "ino-carousel__container" should provide a configurable "aria-label" for expressing meaningful information of the Carousel
5. "ino-carousel-slide" should have role group with the property aria-roledescription set to slide.
6. Each slide has an accessible name provided by a configurable 'aria-label"
7. `<div "ino-carousel__stepper" should implement role="tablist"
8. Each step dot requires role="tab"
9. Each step dot needs an accesible name representing the Slide it selects e.g. aria-label="Slide 2"
10. If the carousel can automatically rotate it requires an explicite button for stopping autmation
11. Keyboard focus as well as hovering via the mouse stops roation
