Fabian Mastenbroek aa3781fde9 mac-virtualcam: Use IOSurface to share output with virtual cameras
This change updates the virtual camera implementation on macOS to
utilize IOSurface to share the output feed with the virtual cameras.

By using IOSurface, we remove the need for copying the frames across
multiple buffers, since they can be shared across Mach connections using
zero-copy.
