Previously, group input values were logged for each group input socket. This
means that each value might be logged many times currently when there are many
Group Input nodes.
This patch changes it so that group input values are only logged for a single
socket. In the provided file from #145385 this speeds up playback performance
from 23 to 39 fps. The next bottleneck there is node editor drawing. If I change
the Geometry Nodes editor to another editor type the speedup is 36 (`main`) to
110 fps (this patch).
