Draft: add wgl_dcomp implementation for OpenGL integration

Work-in-progression directcomposition implementation of wgl.

Sporadically working with glspectrum with the necessary changes in visualization, but still a lot to fix.

It currently cannot be used with playback because it currently requires a d3d11 decoder device, so d3d11 decoder is used and there is no interop for it currently, and none possible from NV12 (so the interop also needs a converter).

I'm not sure whether I can create my own if none are provided by the vout, and the display is forced?

See #26490
