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

Geometry Nodes: initial test trying to use id properties to initialize group inputs The settings can only be set via Python currently. The matching between properties and group inputs is based on the socket identifier (which is e.g. `Input_5`). Maybe we'll have to use a different matching strategy in the future, will see.

Geometry Nodes: store id properties in nodes modifier The properties are not used yet, but can already be accessed with Python using `modifier.settings['setting name']`. The plan is to use id properties to store the parameters that the modifier passes into the geometry node group.

Geometry Nodes: support evaluation with more than one group input Group inputs are not yet exposed in the modifier. For now I just added a simple float setting that will be passed to every float input of the group. Inputs of other types have some default value.

Geometry Nodes: improve node tree evaluation This change reduces the number of unnecessary copies of data and avoids computing the same value more than once.

Geometry Nodes: initial Transform node Most of this code has been written by @HooglyBoogly. I just changed the exec funtion so that it does not have to make a copy of the mesh.

Geometry Nodes: make some function nodes available We might not want to have all those nodes in a final version. Some of them have been added with particle nodes in mind. However, to test the evaluation system it is useful to have a couple of nodes available. Those nodes should "just" work, because their implementation is reused from the particle nodes project.

Geometry Nodes: improve node group evaluation This adds support for nodes that have a multi-function implementation. That includes various function nodes like Math, Combine Vector, ... Furthermore, there is support for implicit conversions now. So it should work when one connects e.g. a float to an integer and vice versa.
