[CSS] Fix :not(:has(...)) invalidation
https://bugs.webkit.org/show_bug.cgi?id=276867
rdar://122689282
Reviewed by Antti Koivisto.
Invalidation of :not(:has(...)) is special because while there can be no
element to actually invalidate, the rule matches.
For ChildChangeInvalidation, we thus propagate the isNegation flag to
StyleInvalidator
to invalidate in case of non-matching the :has().
The other *Invalidation classes handle :not() differently, thus the
isNegation flag is purposedly not propagated to StyleInvalidator for them.
