Reviewed by Tim Horton.

The colorspace argument to IOSurface constructors is currently only used by the CGContext creation
code, except for WebGL which pushes it into IOSurface metadata.

With UI-side compositing on macOS, it's important that the IOSurface colorspace information
survives the trip between processes, so we might as well always push it into IOSurface
metadata.
