Quasar: Add back animation duration prop for QCarousel

[alexeigs]

The slides in QCarousel are animating at a default speed of 300ms (I guess). In the previous version of Quasar we could change that number by adding the following prop like

animation="1000"
Also see the old docs: https://v0-17.quasar-framework.org/components/carousel.html#QCarousel-Vue-Properties

In the current version of the framework this seems to be no longer available which does not allow for custom animation duration when transitioning slides. So far I have also not figured out any other css hacks to change this in QCarousel.

I'd like to request the same thing for the duration of QTabPanels transitions. It might be the same mechanism so I post here. Thanks

I can look into adding this prop.
