@slidy/core: use passive listeners to improve scrolling performance

[iryna-lelyk]

Hi @Valexr,
I have been testing page with sliders in Lighthouse and have gotten report about using passive listeners to improve scroll performance.
This issue was related to @slidy/core package.

So I would really appreciate it if you could add passive modificator for wheel and touch event listeners like this:

document.addEventListener('wheel', onWheel, {passive: true});
