When a transfer request is done to the MetaSelectionSourceRemote source, it's translated to a SelectionTransfer signal, which the remote desktop server is supposed to respond to with SelectionWrite. A timeout (set to 15 seconds) is added to handle too long timeouts, which cancels the transfer request. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1552>
