Associate ::slotted rules with the correct enclosing @layer/@container

RuleSet stores ::slotted rules in a special MinimalRuleData class,
which was introduced for historical reasons [1], but no longer does
anything special now as it simply gets added back to RuleSet for
matching.

MinimalRuleData doesn't store the enclosing @layer or @container rule,
so current implementation mistakenly treats it as unlayered or not in
any container queries.

This patch eliminates the MinimalRuleData class and uses the regular
framework to handle ::slotted rules, and hence make them work with
layers and container queries.
