Geometry Nodes: initial socket inspection

Socket inspection helps with debugging a geometry node group.
Now, when hovering over a socket, a tooltip will appear that provides
information about the data in the socket. Note, socket inspection only
works for sockets that have been computed already. Nodes that are not
connected to an output are not computed.

Future improvements can include ui changes to make the tooltip look
more like in the original design (T85251). Furthermore, additional
information could be shown if necessary.
