A dataDevice has a request to start a drag with multiple parameters. As kwayland's goal is to turn an event-driven API into a property cache API we store this data. This patch moves that storage to the Seat as properties of the active drag, rather than a property of the data device that happened to initialise it. This both helps keep a lot of other logic together, but also allows us to expose a public startDrag method that can be invoked from Kwin's internal surfaces or xwayland. Any properties in DataDevice now relate to data being dropped on the device.
