xdg-toplevel: refactor configure/state flow
Previously, `wlr_xdg_toplevel` didn't follow the usual "current state + pending state" pattern and instead had confusingly named `client_pending` and `server_pending`. This commit removes them, and instead introduces `wlr_xdg_toplevel.scheduled` to store the properties that are yet to be sent to a client, and `wlr_xdg_toplevel.requested` to store the properties that a client has requested. They have different types to emphasize that they aren't actual states.
