style: Simplify selector flags setup even more
In my investigation for bug 1766439, I am digging into why selector matching regressed. It doesn't help that the selector-matching code is instantiated a gazillion times (so there's a ton of copies of the relevant functions). This was needed in the past because we had different ways of setting the selector flags on elements, but I unified that recently and now we only need to either set them or not. That is the kind of thing that MatchingContext is really good for, so pass that instead on MatchingContext creation. Differential Revision: https://phabricator.services.mozilla.com/D145428
