rBb88a37a490fa: Geometry Nodes: new Field at Index node

Summary

This node allows accessing data of other elements on the context geometry (to retrieve data from a different geometry, the Transfer Attribute node should be used).

The node can e.g. be used to generalize what the Edge Vertices node is doing. This node setup does the same as if one would use the "Position 1" output, but it allows retrieving any information from the vertex.

760	I'm not entirely happy with the categories for these two "field" utility nodes, but I don't have another solid idea at the moment. I added that to the agenda for next week.

143	Could consider making this into a template function and using it for the declaration too. Just an idea though, either way is fine with me. We've duplicated this kind of logic so many times already anyway...
