Add `GraphEdit` drag notifications
This commit adds two signals: * connection_drag_begun, which is emitted when a connection is started to be created by the user and * `connection_drag_ended`, which is emitted when no longer a connection is created. Additionally `force_connection_drag_end()` adds the possibility to end the connection dragging. If called from user code, no other connection request signals are invoked. This is useful to add `GraphNode`s via shortcuts while the user is dragging a connection to directly connect the newly added node.
