Message:

[WinCairo][WebKitTestRunner] pixel image dump outputs blank images
​https://bugs.webkit.org/show_bug.cgi?id=198820

Reviewed by Ross Kirsling.

WebView window paints nothing because it is moved out of the
screen. Send WM_PRINT with memory DC instead of WM_PAINT as well
as DumpRenderTree does.

• WebKitTestRunner/win/PlatformWebViewWin.cpp:

(WTR::PlatformWebView::windowSnapshotImage): Send WM_PRINT instead of BitBlt.
