Video previews on shutterstock.com don't play when tapped on iPadOS
https://bugs.webkit.org/show_bug.cgi?id=209903
<rdar://problem/58844166>

Reviewed by Wenson Hsieh.

When tapping on a video preview after searching for a video on shutterstock.com, for instance on https://www.shutterstock.com/video/search/people,
we correctly enter the hover state thanks to our content observation heuristics, but the <video> preview inserted fails to play and show due to a
style rule setting a "display: none" style if the media-query "pointer: coarse" evaluates to true.

In order to improve this website's behavior on iPadOS, we add a new quirk that prevents the "pointer: coarse" media query from evaluating to true.
This new quirk, shouldPreventPointerMediaQueryFromEvaluatingToCoarse(), evaluates to true only for this this website.
