Hans Goudey 740d1fbc4b Geometry Nodes: Log socket values for node tools 
To ease the process of debugging a node group while creating
a node tool, while the group is visible in a node editor, log the socket
values from its last execution. The values are only logged for the
active object is nothing selected. The Viewer node is still not supported
because visualization would probably be very tricky.
