Functions: Run-time type system and index mask This adds a new `CPPType` that encapsulates information about how to handle instances of a specific data type. This is necessary for the function evaluation system, which will be used to evaluate most of the particle node trees. Furthermore, this adds an `IndexMask` class which offers a surprisingly useful abstraction over an array containing unsigned integers. It makes two assumptions about the underlying integer array: * The integers are in ascending order. * There are no duplicates. `IndexMask` will be used to "select" certain particles that will be processed in a data-oriented way. Sometimes, operations don't have to be applied to all particles, but only some, those that are in the indexed by the `IndexMask`. The two limitations imposed by an `IndexMask` allow for better performance. Reviewers: brecht Differential Revision: https://developer.blender.org/D7957

Geometry Nodes: fields and anonymous attributes This implements the initial core framework for fields and anonymous attributes (also see T91274). The new functionality is hidden behind the "Geometry Nodes Fields" feature flag. When enabled in the user preferences, the following new nodes become available: `Position`, `Index`, `Normal`, `Set Position` and `Attribute Capture`. Socket inspection has not been updated to work with fields yet. Besides these changes at the user level, this patch contains the ground work for: * building and evaluating fields at run-time (`FN_fields.hh`) and * creating and accessing anonymous attributes on geometry (`BKE_anonymous_attribute.h`). For evaluating fields we use a new so called multi-function procedure (`FN_multi_function_procedure.hh`). It allows composing multi-functions in arbitrary ways and supports efficient evaluation as is required by fields. See `FN_multi_function_procedure.hh` for more details on how this evaluation mechanism can be used. A new `AttributeIDRef` has been added which allows handling named and anonymous attributes in the same way in many places. Hans and I worked on this patch together.

Geometry Nodes: refactor multi-threading in field evaluation Previously, there was a fixed grain size for all multi-functions. That was not sufficient because some functions could benefit a lot from smaller grain sizes. This refactors adds a new `MultiFunction::call_auto` method which has the same effect as just calling `MultiFunction::call` but additionally figures out how to execute the specific multi-function efficiently. It determines a good grain size and decides whether the mask indices should be shifted or not. Most multi-function evaluations benefit from this, but medium sized work loads (1000 - 50000 elements) benefit from it the most. Especially when expensive multi-functions (e.g. noise) is involved. This is because for smaller work loads, threading is rarely used and for larger work loads threading worked fine before already. With this patch, multi-functions can specify execution hints, that allow the caller to execute it most efficiently. These execution hints still have to be added to more functions. Some performance measurements of a field evaluation involving noise and math nodes, ordered by the number of elements being evaluated: ``` 1,000,000: 133 ms -> 120 ms 100,000: 30 ms -> 18 ms 10,000: 20 ms -> 2.7 ms 1,000: 4 ms -> 0.5 ms 100: 0.5 ms -> 0.4 ms ```

Geometry Nodes: move up destruct instructions in procedure This implements an optimization pass for multi-function procedures. It optimizes memory reuse by moving destruct instructions up. For more details see the in-code comment. In very large fields with many short lived intermediate values, this change can improve performance 3-4x. Furthermore, in such cases, peak memory consumption is reduced significantly (e.g. 100x lower peak memory usage). Differential Revision: https://developer.blender.org/D13548

Geometry Nodes: multi threaded field evaluation This adds a new `ParallelMultiFunction` which wraps another multi-function and evaluates it with multiple threads. The speeds up field evaluation quite a bit (the effect is most noticeable when the number of evaluations and the field is large). There are still other single-threaded performance bottlenecks in field evaluation that will need to be solved separately. Most notably here is the process of copying the computed data into the position attribute in the Set Position node. Differential Revision: https://developer.blender.org/D12457
