(WebKit::PageClientImpl::requestPasswordForQuickLookDocument):
Make the password-related navigation delegates exist on all IOS_FAMILY, not just
where USE(QUICKLOOK) is true, and adopt them for WKPDFView as well. Despite
the names being QuickLook-specific, clients generally want to do the same things
when a password field is up regardless of whether it's up for PDF or QuickLook
reasons.

(-[WKPDFView web_initWithFrame:webView:mimeType:]):
(-[WKPDFView updateBackgroundColor]):
Drive-by; update the background color when entering and exiting the password view.

(-[WKPDFView pdfHostViewControllerDocumentDidRequestPassword:]):
(-[WKPDFView pdfHostViewController:documentDidUnlockWithPassword:]):
Call the navigation delegate.
