Reading or writing a vertex group is expensive enough that it's worth
parallelizing. On a Ryzen 3700x, in a grid of 250k vertices with
30 randomly assigned vertex groups (each to 10-50% of vertices),
I observed a 4x improvement for writing to a group and a 3x
improvement when reading their data. This significantly speeds
up nodes that create a new mesh from a mesh that had vertex groups.
Since 78f28b55d3, allocating on multiple threads is much
faster, making it a nice improvement to parallelize vertex group
operations. This patch adds multi-threading when removing a
vertex group from the "Remove Named Attribute" node.

Before: `(Average: 15.6 ms, Min: 15.0 ms)`
After: `(Average: 8.1 ms, Min: 7.6 ms)`

If we change the radius of a point or spot lamp, we also change the area lamp size.
As shown in T102853, this is bad for animating the lamp type.
The solution is to make the property point to another member of the DNA
struct `Light`.

Use the same `".selection"` attribute for both curve and point domains,
instead of a different name for each. The attribute can now have
either boolean or float type. Some tools create boolean selections.
Other tools create float selections. Some tools "upgrade" the attribute
from boolean to float.
Edit mode tools that create selections from scratch can create boolean
selections, but edit mode should generally be able to handle both
selection types. Sculpt mode should be able to read boolean selections,
but can also and write float values between zero and one.
Theoretically we could just always use floats to store selections,
but the type-agnosticism doesn't cost too much complexity given the
existing APIs for dealing with it, and being able to use booleans is
clearer in edit mode, and may allow future optimizations like more
efficient ways to store boolean attributes.
The attribute API is usually used directly for accessing the selection
attribute. We rely on implicit type conversion and domain interpolation
to simplify the rest of the code.

Partly a cleanup, but also iterating over spans can be faster than
linked lists. Also rewrite the multi-input socket link counting
to avoid the need for a temporary map. Overall, on my setup the changes
save about 5% (3ms) when drawing a large node tree (the mouse house file).
Expose `BKE_pose_apply_action_blend` and a simplified pose backup system
to RNA. This will make it possible to easily create some interactive
tools in Python for pose blending.
When creating a backup via this API, it is stored on the
`Object::runtime` struct. Any backup that was there before is freed
first. This way the Python code doesn't need access to the actual
`PoseBackup *`, simplifying memory management.
The limitation of having only a single backup shouldn't be too
problematic, as it is meant for things like interactive manipulation of
the current pose. Typical use looks like:
- Interactive operator starts, and creates a backup of the current pose.
- While the operator is running:
- The pose backup is restored, so that the next steps always use the
same reference pose.
- Depending on user input, determine a blend factor.
- Blend some pose from the pose library into the current pose.
- On confirmation, leave the pose as-is.
- On cancellation, restore the backup.
- Free the backup.
`BKE_pose_apply_action_blend` is exposed to RNA to make the above
possible.
An alternative approach would be to rely on the operator redo system.
However, since for poses this would use the global undo, it can get
prohibitively slow. This change is to make it easier to prototype
things; further into the future the undo system for poses should be
improved, but that's an entire project on its own.

Move `pose_backup.cc` from `editors/armature` to `blenkernel`. This is
in preparation of an upcoming change where the pose backup is going to be
owned by the `Object`. This will need to be automatically cleared when the
object is freed, which means that `blenkernel` needs the corresponding
logic.
Technically only the freeing code could be moved, but I felt it made more
sense to keep the related code together.
No functional changes.
- Move from blenkernel to the node editor, the only place it was used
- Use two vectors instead of ListBase
- Remove define for validating the clipboard, which shouldn't be skipped
- Comment formatting, other small cleanups to whitespace

When these declarations are built without the help of the special
builder class, it's much more convenient to set them directly rather
than with a constructor, etc. In most other situations the declarations
should be const anyway, so theoretically this doesn't affect safety too
much. Most construction of declarations should still use the builder.
Whenever a node group is entered during evaluation, a new compute
context is entered which has a corresponding hash. When node groups
are entered and exited a lot, this can have some overhead. In my test
file with ~100.000 node group invocations, this patch improves performance
by about 7%.
The speedup is achieved in two ways:
* Avoid computing the same hash twice by caching it.
* Invoke the hashing algorithm (md5 currently) only once instead of twice.
When converting from imesh to mesh for the final result, custom
data should be copied from ALL operands including the main mesh.

This is an obvious editing mistake introduced in 05952aa94d,
resulting in incorrect vertex coordinates used when raycasting
for internal springs with a rest shape key.
Caused by rB6514bb05ea5a.
For the remeshing, we have to make sure these names are brought over
each time a mesh is made from another in the process.
This happens when reprojecting the colors in
`BKE_remesh_reproject_vertex_paint` and also again in
`BKE_mesh_nomain_to_mesh`. A bit unsure if this should happen as deep as
in `BKE_mesh_nomain_to_mesh` (if not, this can be isolated to
`voxel_remesh_exec`), but I would assume other callers of
`BKE_mesh_nomain_to_mesh` would actually benefit from it, too?

When accessing context members from the windowmanager context
(`C->wm.store` which is mainly used for UI related stuff) the above
commit broke behavior in `CTX_store_ptr_lookup` in that it changed and
would **always** return NULL if no type is passed in. The call to
`CTX_store_ptr_lookup` from `ctx_data_get` **always** passes in NULL
though.
Accessing other context members survived since they take a different
code path in `ctx_data_get` and dont use `CTX_store_ptr_lookup`.
Now also return the entry if a NULL type was passed as it was before.

(MacOS) only: In the System tab of the user preferences the user has the
ability to select a GPU backend that Blender will use. After changing
the GPU backend setting, the user has to restart Blender before the
setting is used.
It was added to start collecting feedback on the Metal backend without
using the command lines.
By default Blender will select OpenGL as backend. When Metal is selected
(via `--gpu-backend metal` or via user preferences) OpenGL will be used as
fallback when the platform isn't capable of running Metal.
Separate the "insert nodes into group" operation into more distinct
phases. This helps to clarify what is actually happening, to avoid
redundant updates to group nodes every time a new socket is discovered,
and to make use of the topology cache to avoid the "accidentally
quadratic" alrogithms that we have slowly been removing from node
editing.
The change is motivated by the desire to use dynamic node declarations
for group nodes and group input/output nodes, where it is helpful to
avoid updating the declaration and sockets multiple times.
Propagate `eRNAOverrideMatchResult` 'return' flags at higher level into
BKE API, instead of just returning a boolean true when new override
rules have been created.

This was harmless because the function would just return null in release
builds, which was checked. Theoretically this vertex group mapping
shouldn't depend on the object type, but the vertex group API would
have to move away from the object-level first.
Previously, the same `FieldInferencingInterface` was build for every node
multiple times. Now only once during the inferencing. Going forward,
it would be even better to store the inferencing interface as part of the
node declaration to avoid building it during inferencing at all.
Add documentation for `BKE_id_defgroup_list_get()` and document that
`CD_MDEFORMVERT` mesh layers contain `MDeformVert` structs.
No functional changes.
When creating a new mesh to change it in some way, the active and
default color attribute names should be copied to the new mesh.
Doing that in the generic "copy parameters for eval" function should
cover the vast majority of cases.
Duplicating context lists took a measurable amount of time when drawing
large node trees in the node editor. Instead of using a linked list of
entries, which results in many small allocations, use a vector. Also,
use std::string and StringRefNull instead of char buffers and pointers.
