Subject: Geometry Nodes: Add "Connected" mode to Merge by Distance node

Expose the "Connected" mode from the weld modifier in the
"Merge by Distance" geometry node. This method only merges
vertices along existing edges, but it can be much faster
because it doesn't have to build a KD Tree of all selected
points.
