Reviewed by Hajime Morita.

r122558 introduced injectPagePopupController(), however we'd like to
avoid adding such JavaScript binding code. We can avoid it by exposing a
PagePopupController for a mock and injecting the following code to the
popup document:

<script>window.pagePopupController = window.internals.pagePopupController</script>

No new tests. This is a kind of refactoring.

* testing/InternalSettings.cpp:
(WebCore::InternalSettings::pagePopupController):
Added. Accessor for PagePopupControler owned by the MockPagePopupDriver.
* testing/InternalSettings.h:
(InternalSettings): Declare pagePopupController() for Internals::pagePopupController().
* testing/Internals.cpp:
(WebCore::Internals::pagePopupController):
Added. This uses InternalSettings::pagePopupController().
* testing/Internals.h:
(Internals): Declare pagePopupController() for Internals.idl.
* testing/Internals.idl: Declare pagePopupController.

* testing/MockPagePopupDriver.cpp:
Moved m_pagePopupController from MockPagePopup to MockPagePopupDriver.
(WebCore::MockPagePopup::MockPagePopup):
Added a script element to prepare window.pagePopupController.
Removed a callsite of injectPagePopupController().
(WebCore::MockPagePopupDriver::openPagePopup):
(WebCore::MockPagePopupDriver::closePagePopup):
* testing/MockPagePopupDriver.h:
(WebCore::MockPagePopupDriver::pagePopupController):
Accessor for a PagePopupController object.
(MockPagePopupDriver): Add RefPtr<PagePopupController> data member.

* testing/v8/WebCoreTestSupport.cpp: Remove injectPagePopupController().
* testing/v8/WebCoreTestSupport.h: ditto.
