Reviewed by Ryosuke Niwa.

Use FixedVector instead of Vector in SelectorQuery For SelectorData objects.
We don't need the modify the Vector here. Also use FixedVector::map() to
simplify the code a bit (This required me to rename CSSSelectorList::listSize()
to CSSSelectorList::size() so that it would work with std::size()).

This tested as performance neutral on Speedometer.
