d3d11videosink: Add "gdi-compatible" property

Seungha Yang requested to merge seungha.yang/gstreamer:d3d11-hwnd-window into main

Add new property for application to be able to select swapchain mode. In case of gdi-compatible mode, bitblt swapchain will be used instead of flip mode, and application can perform HWND level interop such as classic GDI. Note that bitblt mode would be less performant than flip mode.
