Simulations: Add simulation node tree type This implements a new builtin node tree type called `SimulationNodeTree`. It is not yet embedded in the `Simulation` data block. The node tree will initially be used for the new particle nodes system. When the cmake option `WITH_NEW_SIMULATION_TYPE` is enabled, a new `Simulation Editor` is shown in the editors menu (which is just a node editor). This patch does not add entries to the Add Node menu, so it is empty. Reviewers: brecht Differential Revision: https://developer.blender.org/D7287

Geometry Nodes: initial scattering and geometry nodes This is the initial merge from the geometry-nodes branch. Nodes: * Attribute Math * Boolean * Edge Split * Float Compare * Object Info * Point Distribute * Point Instance * Random Attribute * Random Float * Subdivision Surface * Transform * Triangulate It includes the initial evaluation of geometry node groups in the Geometry Nodes modifier. Notes on the Generic attribute access API The API adds an indirection for attribute access. That has the following benefits: * Most code does not have to care about how an attribute is stored internally. This is mainly necessary, because we have to deal with "legacy" attributes such as vertex weights and attributes that are embedded into other structs such as vertex positions. * When reading from an attribute, we generally don't care what domain the attribute is stored on. So we want to abstract away the interpolation that that adapts attributes from one domain to another domain (this is not actually implemented yet). Other possible improvements for later iterations include: * Actually implement interpolation between domains. * Don't use inheritance for the different attribute types. A single class for read access and one for write access might be enough, because we know all the ways in which attributes are stored internally. We don't want more different internal structures in the future. On the contrary, ideally we can consolidate the different storage formats in the future to reduce the need for this indirection. * Remove the need for heap allocations when creating attribute accessors. It includes commits from: * Dalai Felinto * Hans Goudey * Jacques Lucke * Léo Depoix

Geometry Nodes: support instancing collections The Point Instance node can instance entire collections now. Before, only individual collections were supported. Randomly selecting objects from the collection on a per point basis is not support, yet. Last part of D9739. Ref T82372.

Geometry Nodes: Initial basic curve data support This patch adds initial curve support to geometry nodes. Currently there is only one node available, the "Curve to Mesh" node, T87428. However, the aim of the changes here is larger than just supporting curve data in nodes-- it also uses the opportunity to add better spline data structures, intended to replace the existing curve evaluation code. The curve code in Blender is quite old, and it's generally regarded as some of the messiest, hardest-to-understand code as well. The classes in `BKE_spline.hh` aim to be faster, more extensible, and much more easily understandable. Further explanation can be found in comments in that file. Initial builtin spline attributes are supported-- reading and writing from the `cyclic` and `resolution` attributes works with any of the attribute nodes. Also, only Z-up normal calculation is implemented at the moment, and tilts do not apply yet. **Limitations** - For now, you must bring curves into the node tree with an "Object Info" node. Changes to the curve modifier stack will come later. - Converting to a mesh is necessary to visualize the curve data. Further progress can be tracked in: T87245 Higher level design document: https://wiki.blender.org/wiki/Modules/Physics_Nodes/Projects/EverythingNodes/CurveNodes Differential Revision: https://developer.blender.org/D11091
