Minimal feature collector for select selectors.
Use a feature collector method that collects necessary features for select
attribute selectors. These selectors can only have element, id, class,
attribute and :not() according to the spec, and no combinators. Blink also
supports pseudo classes for UA shadow DOM.
A motivation here is to be able to collapse
RuleFeatureSet::collectFeaturesFromSelector into the same loop as
updateInvalidationSets now that invalidation sets are always in use.
