Reviewed by Tim Horton.

Use `topPrivatelyControlledDomain` to relax some scenarios in which we currently apply adjustment
underneath `Document::urlForBindings`. We currently avoid adjustment in the case where the current
script triggering the bindings call is first-party (i.e. same origin as the current document), but
this leaves out some cases where it makes more sense to treat certain script is first party; refer
to the new API test case and bug for more information.

(WebCore::Document::urlForBindings const):
(WebCore::Document::mayBeExecutingThirdPartyScript const): Deleted.
