This allows modifiers to have cache pointers that are preserved over undo steps.
I intend to use this for the baked data cache for the geometry nodes modifier.

The function for retrieving a shape key by its index is named
somewhat confusingly, and effectively reimplements BLI_findlink.
However, more importantly, for some reason it is coded to return
null for the index 0 instead of the basis shape key. This severely
limits its usability in some cases.
This refactor replaces the function with a simple strongly typed
wrapper around BLI_findlink, using a different name, and updating
the call sites to check that the index is not 0 where necessary.
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.

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
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.
Design task: #110784
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".

Implements the rest of #101689, after 5e9ea9243b.
- `vdata` -> `vert_data`
- `edata` -> `edge_data`
- `pdata` -> `face_data`
- `ldata` -> `loop_data`
A deeper rename of `loop` to `corner` will be proposed as a next
step, and renaming `totvert` and `totedge` can be done separately.

Instead of keeping track of a local array of positions in the modifier
stack itself, use the existing edit mode SoA "edit cache" which already
contains a contiguous array of positions. Combined with positions as a
generic attribute, this means the state is contained just in the mesh
(and the geometry set) making the code much easier to follow.
To do this we make more use of the mesh wrapper system, where we can
pass a `Mesh` that's actually stored with a `BMesh` and the extra
cached array of positions. This also resolves some confusion-- it was
weird to have the mesh wrapper system for this purpose but not use it.
Since we always created a wrapped mesh in edit mode, there's no need
for `MOD_deform_mesh_eval_get` at all anymore. That function was quite
confusing with "eval" in its name when it really retrieved the original
mesh.
Many deform modifiers had placeholder edit mode evaluation functions.
Since these didn't do anything and since the priority is node-based
deformation now, I removed these. The case is documented more in the
modifier type struct callbacks.
Pull Request: https://projects.blender.org/blender/blender/pulls/108637
Some modifiers used `MOD_deform_mesh_eval_get` to make sure they had
a mesh to retrieve vertex groups from. But since curves don't support
vertex groups anyway, and since the curve to mesh conversion is handled
by the (legacy) curve object modifier stack anyway, this is confusing
and unnecessary. This shouldn't give any behavior changes, but some
deform modifiers on legacy curve objects might be faster if they used
to do the conversion.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
