Make ContentSelectorQuery work when siblings are passed explicitly.
https://bugs.webkit.org/show_bug.cgi?id=96990
Reviewed by Dimitri Glazkov.
When we implement content reprojection in ShadowDOM, we have to pass a node pool to SelectorChecker.
We introdue ShadowDOMSiblingTraversalStrategy, which traverses a node pool instead of real node siblings.
Since ContentSelector is a very hot place, we don't want to regress performance. In the previous patch,
we've make ContentSelector::checkOneSelector template to take SiblingTraversalStrategy as an argument.
We also move DOMSiblingTraversalStrategy to SiblingTraversalStrategies.h.
