Posted after a main queue context merges changes from another context, containing object IDs.
Only use this message type for contexts with `NSMainQueueConcurrencyType`.
For private queue contexts, use ``NSManagedObjectContext/DidMergeChangesAsyncMessage``.
Converts a posted notification into this main actor message type for any observers.
To implement this method in your own `MainActorMessage` 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 `MainActorMessage` or `nil` if conversion is not possible.
