* Source/WebCore/style/CustomFunctionRegistry.cpp:
(WebCore::Style::CustomFunction::CustomFunction):
(WebCore::Style::CustomFunctionRegistry::registerFunction):
Instead of smashing all StyleRuleFunctionDeclarations together eagerly during
registration
we now pair them with their associated container queries so we can resolve them
at
computed style time.

(WebCore::Style::SubstitutionResolver::substituteDashedFunction):
Evaluate any container queries to determine which properties to apply in
function body.

(WebCore::Style::RuleSet::containerQueryForIdentifier):
(WebCore::Style::RuleSet::containerQueryChainFor):
(WebCore::Style::RuleSet::containerQueriesFor):
* Source/WebCore/style/ElementRuleCollector.cpp:
(WebCore::Style::ElementRuleCollector::containerQueriesMatch):
Add helpers for resolving a container query identifier to its wrapping rule
chain.
containerQueriesFor now returns the container rules rather than the queries.
