Geometry Nodes: Add "Point Translate" and "Point Scale" nodes

The translate node moves every point in the geometry, and the scale
node multiplies the "scale" attribute of the input geometry by its input.
While these operations are already possible with the "Attribute" nodes,
these new nodes fit nicely with the nodes specifically for changing the
"rotation" attribute that already exist, and they provide a simpler way
to do the same thing.
