Is your feature request related to a problem? Please describe.

There is currently no way to pass information to MessageDialog callback functions. This precludes tasks like adding stateful controls such as checkboxes, radio buttons, and text boxes to dialogs, without subclassing MessageDialog and implementing a lot of custom logic.

Describe the solution you'd like

Create a Payload data structure to be passed to callback functions. This data structure can have fields added as developer needs are identified, such as #17646 .

Describe alternatives you've considered

See #17646.
