Add getter for a monitor connector

The migration from GdkScreen's monitor API to GdkMonitor left out a way
to get the connector's name of a monitor.

While there's no real guarantee coming from the underlying graphics
system that the connector's name is stable, some system components may
use it to uniquely identify a monitor until the next plug in/out event.
