[:has() perf] Key invalidation RuleSet on invalidation selector
https://bugs.webkit.org/show_bug.cgi?id=312777
rdar://175161107
Reviewed by Alan Baradlay.
We may do unnecessary invalidation because a single invalidation selector
matching can cause
many rules to be evaluated that don't contain that selector.
* Source/WebCore/style/StyleScopeRuleSets.cpp:
(WebCore::Style::ensureInvalidationRuleSets):
Include invalidation selector itself to the hash key when building invalidation
RuleSets.
This also removes the need to do explicit deduping for selectors.
