Jacques Lucke 4d39b6b3f4 Geometry Nodes: skip logging socket values for invisible trees ...

Geometry nodes used to log all socket values during evaluation.
This allowed the user to hover over any socket (that was evaluated)
to see its last value. The problem is that in large (nested) node trees,
the number of sockets becomes huge, causing a lot of performance
and memory overhead (in extreme cases, more than 70% of the
total execution time).

This patch changes it so, that only socket values are logged that the
user is likely to investigate. The simple heuristic is that socket values
of the currently visible node tree are logged.

The downside is that when the user changes the visible node tree, it
won't have any logged values until it is reevaluated. I updated the
tooltip message for that case to be a bit more precise.
If user feedback suggests that this new behavior is too annoying, we
can always add a UI option to log all socket values again. That shouldn't
be done without an actual need though because it takes up UI space.
