Store Target URL in WebContentsDelegateQt::WebContentsCreated

When opening a new window, for example by using the JavaScript
method window.open('...'), the requested url is not stored
in the content::WebContents object we get in
WebContentsDelegateQt::createWindow (at this point, it should
at least be stored as pending request in the WebContents'
NavigationController, but it is not).

Because of this, the QQuickWebEngineNewViewRequest object
in QQuickWebEngineViewPrivate::adoptNewWindow never contained
the url. We have access to the target url in
WebContentsDelegateQt::WebContentsCreated, so now we store
it there in a new property m_initialTargetUrl, from where
WebContentsDelegateQt::createWindow takes it and passes it
to WebContentsAdapter::adoptNewWindow as a new parameter.

[ChangeLog][WebEngine] Fix WebEngineNewViewRequest::requestedUrl being empty when opening window from JavaScript

Task-number: QTBUG-57675
