vo_gpu/d3d11: enable receival of color depth without active backbuffer
Query the description of the swap chain, which should in all theory contain the format of the backbuffer. Then utilize a newly added ra_d3d11 function to map the format to an ra_format. After that, utilize the depth of the first plane of the format, as previously.
