        Add WKPageCopyPendingAPIRequestURL API
        https://bugs.webkit.org/show_bug.cgi?id=53383

        This API returns the last URL requested for load via API, if neither that load nor any
        other load subsequently reaches the provisional state.

        This is useful to be able to track loads initiated via the API

        * UIProcess/API/C/WKPage.cpp:
        (WKPageCopyPendingAPIRequestURL): Retrieve the pending URL.
        * UIProcess/API/C/WKPage.h:
        * UIProcess/WebPageProxy.cpp:
        (WebKit::WebPageProxy::loadURL): Set pending URL.
        (WebKit::WebPageProxy::loadURLRequest): ditto
        (WebKit::WebPageProxy::reload): ditto
        (WebKit::WebPageProxy::goForward): ditto
        (WebKit::WebPageProxy::goBack): ditto
        (WebKit::WebPageProxy::estimatedProgress): Assume the initial
        progress value when there is a pending URL.
        (WebKit::WebPageProxy::didStartProvisionalLoadForFrame): Clear
        pending URL; clients should look at the provisional URL now.
        (WebKit::WebPageProxy::decidePolicyForNavigationAction): Clear
        pending URL if it doesn't match the policy URL; this means we
        were interrupted by another load.
        * UIProcess/WebPageProxy.h:
        (WebKit::WebPageProxy::pendingAPIRequestURL): Helper function.
        (WebKit::WebPageProxy::clearPendingAPIRequestURL): ditto
        (WebKit::WebPageProxy::setPendingAPIRequestURL): ditto
