binding: Calls didAccessInitialDocument() for a returned Window.

Calls didAccessInitialDocument() as soon as we return
a Window object that is not top/parent/self/window/frames.

As long as it's possible to access to the document of
a window with bypassing securityCheck() in V8Window.cpp,
we need to check the access to the initial document as
soon as we return a Window object.

top/parent should be already checked, so we don't need
this check there.  self/window/frames return itself, so
we don't need the check there, either.
