This moves `MOD_meshsequencecache.c` to C++ and fixes compile warnings
introduced from the change. This uses C++ style casts, as well as
`nullptr` instead of `NULL`.
This will allow to output `GeometrySets` from the modifier, which is C++.

Currently there is a "calc_face_normal" argument to mesh to bmesh
conversion, but vertex normals had always implicitly inherited whatever
dirty state the mesh input's vertex normals were in. Probably they were
most often assumed to not be dirty, but this was never really correct in
the general case.
Ever since the refactor to move vertex normals out of mesh vertices,
cfa53e0fbe, the copying logic has been explicit: copy the
normals when they are not dirty. But it turns out that more control is
needed, and sometimes normals should be calculated for the resulting
BMesh.
This commit adds an option to the conversion to calculate vertex
normals, true by default. In almost all places except the decimate
and edge split modifiers, I just copied the value of the
"calc_face_normals" argument.

Since 3b6ee8cee7, a list of vertex groups cannot be retrieved
from curve objects for merging because curve objects do not support
vertex groups. Previously the empty list on the object was returned.
Only mesh objects are supported for the caps.
This commit removes the implementations of legacy nodes,
their type definitions, and related code that becomes unused.
Now that we have two releases that included the legacy nodes,
there is not much reason to include them still. Removing the
code means refactoring will be easier, and old code doesn't
have to be tested and maintained.
After this commit, the legacy nodes will be undefined in the UI,
so 3.0 or 3.1 should be used to convert files to the fields system.
The net change is 12184 lines removed!
The tooltip for legacy nodes mentioned that we would remove
them before 4.0, which was purposefully a bit vague to allow
us this flexibility. In a poll in a devtalk post showed that the
majority of people were okay with removing the nodes.

So far it was needed to declare a new RNA struct to `RNA_access.h` manually.
Since 9b298cf3db we generate a `RNA_prototypes.h` for RNA property
declarations. Now this also includes the RNA struct declarations, so they don't
have to be added manually anymore.

This fix contains two parts. There was one critical mistake where
order of two indices was wrong when removing constraint planes from
the array. The other changes are improvements to the used thresholds
to keep everything numerically stable.

In some cases, the normal edit modifier calculated the normals on one
mesh with the "ensure" functions, then copied the mesh and retrieved
the layers "for write" on the copy. Since 59343ee162, normal
layers are never copied, and normals are allocated with malloc instead
of calloc, so the mutable memory was uninitialized.
Fix by calculating normals on the correct mesh, and also add a warning
to the "for write" functions in the header.
These features are complicated to support on GPU and hardly compatible
with subdivision in the first place. In the future, with T68891 and
T68893, subdivision and custom smooth shading will be separate workflows.
For now, and to better prepare for this future (although long term
plan), we should discourage workflows mixing subdivision and custom
smooth normals, and as such, this disables GPU subdivision when
autosmoothing or custom split normals are used.
This also adds a message in the modifier's UI to indicate that GPU
subdivision will be disabled if autosmooth or custom split normals are
used on the mesh.

These were only set in two places. One was related to "tessellated loop
normal", and the other derived corner normals. The values were never
checked though, after 59343ee162. The handling of dirty face
corner normals is clearly problematic, but in the future it should be
handled like the normal layers on the other domains instead.

The modifier supports arithmetic operations, like Add or Multiply,
but for some reason omits Minimum and Maximum. They are similarly
simple and useful math functions and should be supported.

It's better not to expose the details of where the dirty flags are
stored to every place that wants to know if the normals are dirty.
Some of these places are relics from before vertex normals were
computed lazily anyway, so this is more of an incrememtal cleanup.
This will make part of the fix for T95839 simpler.
This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.

To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

The crash is caused as we did not check that the RNA pointer is null
before trying to use it. This moves the existing checks from the
modifier panels into the template functions so the logic is a bit
centralized.

Complex Solidify creates edge bevel weights on the rim if the
according vertex has some vertex bevel weight. If there are no
edge bevel weights, they were left disabled even if vertex bevel
weights are used.
Technically, this can't be relied upon in the long term. It worked more or
less accidentally before. It was broken by a previous fix accidentally. I mainly
bring it back because rBa985f558a6eb16cd6f0 was not expected to have
this side effect.
Note, this change can result in slower performance. Writing to a vertex
groups is less efficient than using a generic attribute.
The issue was happening with a specific file where the ID management
code was not fully copying all modifiers because of the extra check
in the `BKE_object_support_modifier_type_check()`.
While it is arguable that copy-on-write should be a 1:1 copy there is
no real need to maintain the per-modifier pointer to its original.
Use its SessionUUID to perform lookup in the original datablock.
Downside of this approach is that it is a linear lookup instead of
direct pointer access, but the upside is that there is less pointers
to manage and that the file with unsupported modifiers does behave
correct without any asserts.

This refactors how output attributes are computed in the geometry
nodes modifier. Previously, all output attributes were computed one
after the other. Every attribute was stored on the geometry directly
after computing it. The issue was that other output attributes might
depend on the already overwritten attributes, leading to unexpected
behavior.
The solution is to compute all output attributes first before changing the
geometry. Under specific circumstances, this refactor can result in a speedup,
because output attributes on the same domain are evaluated together now.
Overwriting existing might have become a bit slower, because we write the
attribute into new buffer instead of using the existing one.

The geometry nodes modifier currently always adds a dependency
relation from the evaluated geometry to the object transform. However,
that can be avoided unless there is a collection or object info node in
"Relative" mode.
In order to avoid requiring dependency graph relations updates often
when editing a node tree, this patch doesn't check if the node is muted
or if the data-block sockets are empty before adding the dependency.
