With this commit, node warnings added to nodes during evaluation
(not "Info" warnings) will also draw in the modifier. In the future
there could be a "search for this node" button as well.

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.

Many ui features for geometry nodes need access to information generated
during evaluation:
* Node warnings.
* Attribute search.
* Viewer node.
* Socket inspection (not in master yet).
The way we logged the required information before had some disadvantages:
* Viewer node used a completely separate system from node warnings and
attribute search.
* Most of the context of logged information is lost when e.g. the same node
group is used multiple times.
* A global lock was needed every time something is logged.
This new implementation solves these problems:
* All four mentioned ui features use the same underlying logging system.
* All context information for logged values is kept intact.
* Every thread has its own local logger. The logged informatiton is combined
in the end.
