[Chris Dumez]

Add C API to retrieve the original page of a WKDownload. This is the C API equivalent to _WKDownload.originatingWebView in ObjC.

will nullptr not work?

It would be nice if we could remove this PageClient call completely and make all platforms do this the same way.  It seems like that's all GTK is doing here, and WPE is in progress.
