  Propagate scope element into :has CheckingContext

Reviewed by Tim Nguyen and Antti Koivisto.

In https://bugs.webkit.org/show_bug.cgi?id=261320 we split out
CheckingContext::scope into two separate fields: "scope" for the element
that matches :scope, and "hasScope" for the scope of a :has()
pseudo-class.

We need to propagate scope into the child CheckingContext we create for
:has() pseudo-class matching, otherwise :has(:scope) will never match
anything.
