Aitor Gómez García 1ccd9aa91c CGA video: move CGA to a dedicated UM6845R-safe scandoubler 
Split the CGA scan-doubling path into a dedicated video_scandoubler block instead of relying on the previous shared path.

This keeps the output timing stable for the CGA pipeline and avoids CRTC-sensitive behaviour seen with UM6845R-compatible software and demos.
