Add Windows Graphics Capture (WGC) API based screen capture mode. The conditions where this mode is used: * Explicitly requested by user (capture-api property) * To capture specific window * When DXGI desktop duplication API does not work on hybrid graphics systems (e.g., multi-gpu laptop) Full features of this implementation require Windows 11. And Windows 11 SDK is required to build this feature. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3144>
