remote-desktop/session: Add support for SelectionTransfer/Write

Browse Source 
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.
