Make error messages for cross-domain access OOPIF-friendly.

      * Make crossDomainAccessErrorMessage and
  sanitizedCrossDomainAccessErrorMessage non-virtual members of
  DOMWindow, and tweak the logic to also work on RemoteDOMWindows
  using replicated origins.

* Change BindingSecurity::shouldAllowAccessToFrame to actually throw
  exceptions when encountering a RemoteFrame.  Previously, we returned
  false without throwing exceptions, which was breaking expectations
  for layout tests when running with --site-per-process.

BUG=478254,477150

TEST=Run
http/tests/security/cross-frame-access-set-window-properties.html with
--site-per-process, and ensure the calls that are supposed to throw
exceptions actually do so.
