Revert of bindings: Do not use ScriptWrappable::wrap for RemoteDOMWindow.

Revert of bindings: Do not use ScriptWrappable::wrap for RemoteDOMWindow. (patchset #4 id:60001 of https://codereview.chromium.org/1100693002/)

Reason for revert:
This causes the following test to fail:
out/Release/browser_tests --gtest_filter=ActivityLogApiTest.TriggerEvent
This is preventing Blink from rolling:

Original issue's description:
> bindings: Do not use ScriptWrappable::wrap for RemoteDOMWindow.
> 
> Custom toV8(EventTarget*) has been handling LocalDOMWindow in a special
> manner so that custom toV8(DOMWindow*) is always used.  However, when
> RemoteDOMWindow, and DOMWindow as their superclass, were introduced, we
> didn't add the same support for RemoteDOMWindow nor DOMWindow.  It was
> wrong.
> 
> When toV8(EventTarget*) is called with a RemoteDOMWindow before
> installDOMWindow is called, toV8(EventTarget*) calls
> RemoteDOMWindow::wrap() and it creates a wrapper.  After that, when
> installDOMWindow is called, the wrapper already exists for the
> RemoteDOMWindow and it causes crash.
> 
> I think this is the cause of mysterious crashes around installDOMWindow.
> 
> This CL fixes:
> - Makes sure that DOMWindow::wrap is never called.
> - Calls toV8(DOMWindow*) for not only LocalDOMWindow but also
>   RemoteDOMWindow.
> 
> I've confirmed that crash occurs at www.nhl.com with --site-per-process
> specified, and fix with this CL.
