  WinCairo WK1 DumpRenderTree: Pixel dump support in accelerated compositing mode
https://bugs.webkit.org/show_bug.cgi?id=247479

Reviewed by Don Olmstead.

WinCairo DumpRenderTree hadn't supported pixel dump in accelerated
compositing mode. WM_PAINT event should paint contents into the HDC
even in accelerated compositing mode. Implemented it by painting into
a BitmapTextureGL and reading back.
