This creates platform-dependent monitors to detect when the system time zone changes. On Linux, we use a file watcher to monitor files such as /etc/localtime for changes. On macOS, this uses CFNotificationCenter to be notified by the OS when the time zone changes. Note: the macOS implementation requires running in a process which is running the CoreFoundation event loop. Both the AppKit and Qt chromes are doing so in the UI process, but this means we cannot run this monitor in the WebContent process.
