Inlining the functions is simpler nowadays, since there are utility
functions to copy spans and tag the mesh caches dirty. Also use an
array instead of a raw pointer for multires.
Resolves#103789
Implement the next phases of bounds improvement design #96968.
Mainly the following changes:
Don't use `Object.runtime.bb` for performance caching volume bounds.
This is redundant with the cache in most geometry data-block types.
Instead, this becomes `Object.runtime.bounds_eval`, and is only used
where it's actually needed: syncing the bounds from the evaluated
geometry in the active depsgraph to the original object.
Remove all redundant functions to access geometry bounds with an
Object argument. These make the whole design confusing, since they
access geometry bounds at an object level.
Use `std::optional<Bounds<float3>>` to pass and store bounds instead
of an allocated `BoundBox` struct. This uses less space, avoids
small heap allocations, and generally simplifies code, since we
usually only want the min and max anyway.
After this, to avoid performance regressions, we should also cache
bounds in volumes, and maybe the legacy curve and GP data types
(though it might not be worth the effort for those legacy types).

Currently we have options to transfer the paint mask, face sets, and
color attributes to the new mesh created by voxel remesh. This doesn't
make use of the generic attribute design, where it would be clearer to
transfer all attributes with the same methods. That's reflected in the
code as well-- we do duplicate work for the mask and vertex colors, for
example.
This commit replaces the transfer options with a single checkbox for
all attributes. All attribute types on all domains are transferred with
basically the same method as the "Sample Nearest" node from geometry
nodes-- they take the value from the nearest source element of the same
domain. Face corners are handled differently than before. Instead of
retrieving the mixed value of all the corners from the nearest source
vertex, the value from the nearest corner of the nearest face.
---
Some timing information, showing that when interpolating the same
data, the attribute propagation is significantly faster than before.
Edge and corner attributes would add some cost (edges more than
corners), but might not always be present.

Slightly non-trivial linked collections hierarchy could cause 'Make
LibOverride' operation from 3DView fail, reporting that more than one
potential root collections were found.
Logic here was way to simple, now this error should only happen when
there are effectively more than one potential 'good' root collection
(i.e. when two unrelated collections both contain (directly or not) the
selected objects(s).
Move object runtime data to a separate header and allocate it separately
as `blender::bke::ObjectRuntime`. This is how node, mesh, curves, and
point cloud runtime data is stored.
Benefits:
- Allow using C++ types in object runtime data
- Reduce space required for Object struct in files
- Increase conceptual separation between DNA and runtime data
- Remove the need to add manual padding in runtime data
- Include runtime struct definition only in files that require it

The distinction would start to become meaningless when we use C++
features in the older C header. The naming and lack of a proper
namespace should be enough to clarify the separation for now.
In Blender 4.0 Grease Pencil was showing up as "Grease Pencil (legacy)" in the UI in some places.
Since the current Grease Pencil is not replaced yet, it shouldn't be named this way in 4.0.

No functional changes.
Moving the following functions
`action_fcurve_ensure` and
`action_fcurve_find`
from
`ANIM_fcurve.hh`/`fcurve.cc`
to
`ANIM_action.hh`/`action.cc`
This is an effort to ensure that the fcurve files don't need to know
about the container they are stored in so we can swap out
the container more easily.

No functional changes.
Since the following functions are now in a C++ namespace, their prefix can be removed:
* ANIM_setting_get_rna_values -> get_rna_values
* ED_action_fcurve_find -> action_fcurve_find

Design task: #93551
This PR replaces the auto smooth option with a geometry nodes modifier
that sets the sharp edge attribute. This solves a fair number of long-
standing problems related to auto smooth, simplifies the process of
normal computation, and allows Blender to automatically choose between
face, vertex, and face corner normals based on the sharp edge and face
attributes.
Versioning adds a geometry node group to objects with meshes that had
auto-smooth enabled. The modifier can be applied, which also improves
performance.
Auto smooth is now unnecessary to get a combination of sharp and smooth
edges. In general workflows are changed a bit. Separate procedural and
destructive workflows are available. Custom normals can be used
immediately without turning on the removed auto smooth option.
**Procedural**
The node group asset "Smooth by Angle" is the main way to set sharp
normals based on the edge angle. It can be accessed directly in the add
modifier menu. Of course the modifier can be reordered, muted, or
applied like any other, or changed internally like any geometry nodes
modifier.
**Destructive**
Often the sharp edges don't need to be dynamic. This can give better
performance since edge angles don't need to be recalculated. In edit
mode the two operators "Select Sharp Edges" and "Mark Sharp" can be
used. In other modes, the "Shade Smooth by Angle" controls the edge
sharpness directly.
### Breaking API Changes
- `use_auto_smooth` is removed. Face corner normals are now used
automatically if there are mixed smooth vs. not smooth tags. Meshes
now always use custom normals if they exist.
- In Cycles, the lack of the separate auto smooth state makes normals look
triangulated when all faces are shaded smooth.
- `auto_smooth_angle` is removed. Replaced by a modifier (or operator)
controlling the sharp edge attribute. This means the mesh itself
(without an object) doesn't know anything about automatically smoothing
by angle anymore.
- `create_normals_split`, `calc_normals_split`, and `free_normals_split`
are removed, and are replaced by the simpler `Mesh.corner_normals`
collection property. Since it gives access to the normals cache, it
is automatically updated when relevant data changes.
Addons are updated here: https://projects.blender.org/blender/blender-addons/pulls/104609
### Tests
- `geo_node_curves_test_deform_curves_on_surface` has slightly different
results because face corner normals are used instead of interpolated
vertex normals.
- `bf_wavefront_obj_tests` has different export results for one file
which mixed sharp and smooth faces without turning on auto smooth.
- `cycles_mesh_cpu` has one object which is completely flat shaded.
Previously every edge was split before rendering, now it looks triangulated.

No functional changes
Since the functions now live in a namespace,
they no longer need the prefix
as a result there are now 2 functions named
`autokeyframe_object`
which is fine because they take different parameters
If both are needed is for a future patch to investigate

No functional changes
The following functions have been moved
`autokeyframe_cfra_can_key`
`autokeyframe_object`
`ED_autokeyframe_object`
`ED_autokeyframe_pchan`
`ED_autokeyframe_property`
they are all in a new file
keyframing_auto.cc
while the declarations are in
ANIM_keyframing.cc
The autokeyframe makros also have been moved

Update to the new naming convention for `Light Probes`:
`Reflection Cubemap` -> `Sphere`
`Reflection Plane` -> `Plane`
`Irradiance Grid` -> `Volume`
Note that this breaks the Python API (`bpy.types.LightProbe.type`).

Move the three current 'status variables' (stop, update and progress)
into a single 'WorkerStatus' struct. This is cleaner and will allow for
future workin this area without having to edit tens of 'startjob'
callbacks signatures all the time.
No functional change expected here.
Note: jobs' specific internal code has been modified as little as
possible, in many cases the job's own data still just store pointers to
these three values. Ideally in the future more refactor will be using a
single pointer to the shared `wmJobWorkerStatus` data instead.

This replaces the older dynamic c arrays with blender::Vector as
appropriate. Many files required minimal changes and the before/after
are quite similar.
There's 3 remaining usages of the old machinery but those will require
more involved changes and design.

If an armature is present, but not active the group_select_mode defaults to WT_VGROUP_BONE_DEFORM, and throws an error because it can't find any active vertex groups. we're now checking to see if any bone is actively deforming before switching to WT_VGROUP_BONE_DEFORM (else defaulting to WT_VGROUP_ALL)
