Add a new video source element "d3d11desktopdupsrc" for capturing desktop image via Desktop Duplication based on Microsoft's Desktop Duplication sample available at https://github.com/microsoft/Windows-classic-samples/tree/master/Samples/DXGIDesktopDuplication This element is expected to be a replacement of existing dxgiscreencapsrc element in winscreencap plugin. Currently this element can support (but dxgiscreencapsrc cannot) - Copying captured D3D11 texture to output buffer without download - Support desktop session transition e.g., can capture desktop without error even in case that "Lock desktop" and "Permission dialog" - Multiple d3d11desktopdupsrc elements can capture the same monitor Not yet implemented features - Cropping rect is not implemented, but that can be handled by downstream - Mult-monitor is not supported. But that is also can be implemented by downstream element for example via multiple d3d11desktopdup elements with d3d11compositor Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1855>
