Bug 1646266 - NoPayload default type, with specialized empty helper - r=gregtatum
`NoPayload` will be mostly used internally when adding markers without payload data. It has an empty specialization of the MarkerTypeHelper (mainly to catch misuses), and the add-marker code will need to have different compile-time paths to handle it.
