This converts the public `uiItemFullO` function to an object oriented
API (an `uiLayout::op` overload), matching recents changes in the API.
Changes includes the removal of the paramether `IDProperty *properties`
that seems unused (all places just sets `nullptr`, can be added as last
argument with `nullptr` as default value though), and instead of using a
return paramether the function now returns the pointer to write properties.

This merges the public `uiItemS` and `uiItemS_ex` functions into an
object oriented API (`uiLayout::separator`), matching the python API.
This reduces the difference between the C++ API with the python version,
its also helps while converting code from python to C++ code
(or vice-versa), making it almost seamless.

The old name `modifier_panel_end` was not great because:
* There is no corresponding `*_begin`.
* It sounds more magical then it really is (it just draws the error message).
* It doesn't even have to be at the end as is sometimes the case when there are subpanels.

This converts the public `uiItemO` function to an object oriented
API (`uiLayout::op`).
Also this rearranges `idname` paramether, since this the only one
required, and to make format similar to `uiItemFullO`
Note: One of the benefits of moving from a public function to class
method is to reduce API usage difference between C++ and Python. In
Python this method is called `UILayout::operator`, however `operator`
is a reserved keyword in C++.

The main issue of 'type-less' standard C allocations is that there is no check on
allocated type possible.
This is a serious source of annoyance (and crashes) when making some
low-level structs non-trivial, as tracking down all usages of these
structs in higher-level other structs and their allocation is... really
painful.
MEM_[cm]allocN<T> templates on the other hand do check that the
given type is trivial, at build time (static assert), which makes such issue...
trivial to catch.
NOTE: New code should strive to use MEM_new (i.e. allocation and
construction) as much as possible, even for trivial PoD types.
Previously we generally expected CustomData layers to have implicit
sharing info, but we didn't require it. This PR clarifies that we do
require layers with non-null data to have implicit sharing info. This
generally makes code simpler because we don't have to have a separate
code path for non-shared layers. For example, it makes the "totelem"
arguments for layer freeing functions unnecessary, since shared data
knows how to free itself. Those arguments are removed in this PR.

The Subdivision Modifier used "Levels" and the Multiresolution Modifier used "Level". This difference is changed to be "Levels" for both, which aligns with similar UI terminology where plural forms indicate adjustable values, such as "Render Samples".

Move `CD_CUSTOMLOOPNORMAL` to the newly added
`CD_PROP_INT16_2D` generic attribute type. This is similar to
previous commits moving specific custom data types.
The attribute name is `custom_normal`. When the attribute with
that name is on the face corner domain, the code will interpret it
as stored in the existing deformation-invariant spherical coordinate
space.
The API remains the same, with the additional opportunity to edit
custom normal data as an attribute directly (which admittedly is fairly
unintuitive currently).
See #130484.

Remove some uses of the `SculptSession` array in favor of retrieving
positions as necessary. Because of implicit sharing, avoiding unnecessary
mutable references to data can avoid copies and increased memory usage.
There are still more places to change before sculpt mode recieves that
benefit though.
The crash was caused by attempting to write-back to the original data after it
has been removed (`add_data_block_items_writeback`).
This write-back is already disabled when applying a modifier, however the
corresponding flag was only set when applying modifiers on mesh objects. This
patch fixes this issue with two small changes:
* Rename `MOD_APPLY_TO_BASE_MESH` to `MOD_APPLY_TO_ORIGINAL` to make it more
generic.
* Pass this flag into modifier evaluation for other geometry types besides
meshes in `modifier_apply_obdata`.

This commit moves generated `RNA_blender.h`, `RNA_prototype.h` and
`RNA_blender_cpp.h` headers to become C++ header files.
It also removes the now useless `RNA_EXTERN_C` defines, and just
directly use the `extern` keyword. We do not need anymore `extern "C"`
declarations here.

Move most code to `blender::bke::subdiv`. That helps organization
and makes using C++ in subdiv code easier, which will be useful for
removing the unnecessary opensubdiv C-API wrapper.
Because normals are calcualted lazily for all cases "depends_on_normals"
except for BMesh original normals, this is mostly unnecessary. It's actually
probably not necessary at all, because in practice there is always a separate
positions array stored in `EditMeshData` during mesh edit mode modifier
evaluation, bringing us back to the lazy calculation. But anyway, removing
the usage for topology-changing modifiers and modifiers which don't
accept BMesh as input anyway simplifies things.

This allows modifiers to have cache pointers that are preserved over undo steps.

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

Some common headers were including this. Separating the includes
will ideally lead to better conceptual separation between CustomData
and the attribute API too. Mostly the change is adding the file to
places where it was included indirectly before. But some code is
shuffled around to hopefully better places as well.
Use the standard "elements_num" naming, and use the "corner" name rather
than the old "loop" name: `verts_num`, `edges_num`, and `corners_num`.
This matches the existing `faces_num` field which was already renamed.

Automatic memory management and clearer ownership! Requires
removing `MEM_CXX_CLASS_ALLOC_FUNCS` from `MeshRuntime`,
but that's used very inconsistently anyway, and `MeshRuntime` isn't

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.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.

Ref !110783.
Previously the panel type name of a modifier (e.g. "MOD_PT_Smooth") was
created by copying from the ModifierTypeInfos name.
This meant that modifiers with the same default name would use
the same identifier for the panels.
Since different object types (e.g. OB_GREASE_PENCIL and OB_MESH)
might want to use the same default modifier name, this PR introduces
an idname field in the ModifierTypeInfo struct. This is then used to
generate the panel type name.
For compatibility reasons, the idname is the same as the name for now.
Note: Because the name was used previously, this means that some
modifiers have spaces in their panel type name.
E.g. "MOD_PT_Volume to Mesh".
