Only run "perform a security check" for Window and Location objects

These days all implementations only have security checks on a couple of objects. Firefox used to have cross-origin object wrapper, but those are no longer web observable.

Tests: html/browsers/origin/cross-origin-objects/cross-origin-objects.html and web-platform-tests/wpt#20432.
