More progress converting the point distribute node to operations

I might not continue with this approach, it seems like building a
temporary vector of geometry components will be much simpler

Merge branch 'master' into temp-geometry-nodes-instances-api

WIP: Rewrite point distribute node to correctly support instances

This does not compile, and isn't close to finished.

Add a second idea for the instances API

Merge branch 'master' into temp-geometry-nodes-instances-api

Merge branch 'master' into temp-geometry-nodes-instances-api

Geometry Nodes: Support instances in the point instance node

Geometry Nodes: Output instanced geometry from the object info node

Geometry Nodes: First pass on instance geometry set API

I think a fair amount of this will change, but this API uses a callback on
each component of a geometry set and its instances recursively.

Example uses will come in a following commit.
