A message the system sends when the device's thermal state changes.
To observe this message, access the ``ProcessInfo/thermalState`` property prior to adding your observer.
Observe this message with the identifier ``NotificationCenter/MessageIdentifier/thermalStateDidChange``, or specify its type directly to the `addObserver(of:for:using:)` method.
The ``NotificationCenter/MainActorMessage/Subject`` of this message type is ``ProcessInfo``.
This message interoperates with the notification ``ProcessInfo/thermalStateDidChangeNotification``.
The system notifies observers of the message when the ``NotificationCenter`` posts the notification.
Similarly, the system notifies observers of the notification when it posts the message.
Converts a posted notification into this asynchronous message type for any observers.
To implement this method in your own `AsyncMessage` conformance, retrieve values from the ``Notification``'s ``Notification/userInfo`` and set them as properties on the message.
- Parameter notification: The posted ``Notification``.
- Returns: The converted `AsyncMessage`, or `nil` if conversion is not possible.
