Geometry Nodes: Support pointcloud in transform node

This is likely not the final implementation of the transform node, but
it's a good trivial case for supporting multiple geometry data types.

Fix group input is resetting in modifier

Fix missing null check in recent commit

Cleanup: Use proper C++ types

Geometry Nodes: initial support for bool group inputs

Still need to work on the uilayout inside the modifier.

Geometry Nodes: support vector inputs to geometry group

Geometry Nodes: initial support for displaying group inputs in modifier

This uses the previously added id properties on the nodes modifier
to store values that are passed into the geometry node group.

Geometry Nodes: enable nodes modifier in edit mode

Geometry Nodes: Fix memory leak

Geometry Nodes: Add initial scattering nodes

The first is a "Point Distribute" node, which takes a mesh and outputs a
pointcloud, scattering points randomly on the surface based on the input
density. The distribution algorithm is extremely basic at this point, and
doesn't take into account an attribute weight at each vertex.

The second node is a "Point Instance" node, which is mainly a placeholder
until the engineering design for how to work with instancing in geometry
nodes is decided. For now it just runs the same code that the convert
pointcloud to mesh operator uses.

Geometry Nodes: Add function to create a temporary pointcloud

We needed a "nomain" funciton similar to the one we have for meshes in
order to add a working pointcloud for the geometry nodes.

Geometry Nodes: Add utility to position point randomly on 3D triangle

Geometry Nodes: Add pointcloud support to geometry class

This adds another set of the same mesh functions but for pointclouds.
There are probably better ways to generalize this functionality, but that
may have to be rethought in the future anyway if we want to store
multiple of each type. And anyway it's handy to have a specific set of
"pointcloud" functions available in the node implementations.

Geometry Nodes: Initial mesh boolean node

This uses the code from the rewritten boolean modifier from 2.91 as a node.
The implementation is about as minimal as it can get, since for now the use
case of this node is mostly to test multiple geometry outputs and inputs.

The boolean code requires a BMesh, so the node converts the input meshes
to BMesh, so the bmesh is added as a dependency to the nodes module.

Cleanup: remove unused modifier property
