Geometry Nodes: Add "Location" output to Attribute Proximity node

This patch adds an output field to the Attribute Proximity node and
renames the existing string socket from "Result" to "Distance".
  - The "Distance" output contains distance to the closest position
    on the Target geometry.
  - The new "Location" output contains the coordinates of the closest
    position on the Target geometry.

A basic use case for this data is a simple shrinkwrap operation.
