CSS: Fix :visited behavior for SubSelectors
https://bugs.webkit.org/show_bug.cgi?id=135324

Reviewed by Benjamin Poulain.

Disable :visited match for the selectors that has SubSelectors.

Source/WebCore:

Tests: fast/history/nested-visited-test-complex.html
       fast/history/sibling-visited-test-complex.html

* css/SelectorChecker.cpp:
(WebCore::SelectorChecker::matchRecursively):

LayoutTests:
This `isSubSelector` (`context.firstSelectorOfTheFragment == context.selector`) is intended to
check `relation != CSSSelector::SubSelector`.
But since this value belongs to the previous selector and it is tested inside the branch that checks
the next selector isn't SubSelector `relation != CSSSelector::SubSelector`,
this only matches when the previous selector doesn't has SubSelectors.
