perf: strip OpenCV ffmpeg DLL and PyWin32 help from portable build

- Remove opencv_videoio_ffmpeg (28MB) — only needed for video file I/O,
  camera capture uses cv2.VideoCapture which links directly to DirectShow
- Remove PyWin32.chm help file (2.6MB)
- Keep cv2.pyd intact (needed for resize, cvtColor, camera)

Future: migrate non-camera cv2 usage to Pillow, replace winsdk (37MB
monolithic binary) with lighter notification API.
