Records the {StartupState} of the {Counter} in the {ProcessType} process on macOS. This is polled periodically using proc_pidinfo(..., PROC_PIDTASKINFO, ...). Recorded once every 30 seconds for the browser, GPU, and network processes, and once every 30 seconds for every 1/20th renderer or utility process.
