Geometry Nodes: Optimise Voronoi texture node

This patch improves performance by only assigning
or calculating data for connected sockets.

It is recommended that artists use the lowest dimensions setting
for noise based textures. E.g. Use 2D instead of 3D where possible.

Using a scoped timer and single thread on 256,000 points.
Smooth F1 3D : Debug build
Timer 'Optimised' took 9.39991 s
Timer 'Normal' took 16.1531 s

This optimisation is only for GN and not shaders.
