style: Record attribute dependencies within the selector list of :nth-child(... of <selector list>)
There are separate filters for IDs, classes, attribute local names, and
element state.
Also, we invalidate siblings of elements matched against the selector
list of :nth-child(... of <selector list>) by marking matched elements
with NODE_HAS_SLOW_SELECTOR_NTH_OF.
The only remaining invalidation case invalidation case is
`:nth-child(An+B of :has())` (bug 1818155), which should not block
shipping `layout.css.nth-child-of.enabled`, because :has(...) is still
being implemented (bug 418039).
Depends on D172352
