This will break downstream code.  Please don't do this yet.

I'm not sure I understand this... Can you elaborate on what you mean here? Maybe
that we should wait to plumb the connector before doing this? Or that
implementers of ozone_platform.h may not have the with-parameter version? As I
see the parameter-less InitializeForGPU already sets single_process = false and
connector = nullptr by default, so I'm not sure why it would be a problem.
