remote-desktop/eis: Add support for ConnectToEIS.

Browse Source 
Remote desktop version 2 added a new method ConnectToEIS .

ConnectToEIS allows clients to requests a file descriptor from the
compositor which can then be used directly from libei.

Once established, the communication between compositor and application
is direct, without the need to go through the portal process(es).
