Since we have a node that sets a mesh's auto smooth angle
(unfortunately, in retrospect), we generally can't assume at all
that value is the same as whatever input mesh. Similar asserts
were removed previously in 8216b759e9. While the attempt
at assertions to clarify assumptions is noble, this one doesn't
make sense anymore.
I found this while investigating T95479.

This commit adds infrastructure for 8 bit signed integer attributes.
This can be useful given the discussion in T94193, where we want to
store spline type, Bezier handle type, and other small enums as
attributes.
This is only exposed in the interface in the attribute lists, so it
shouldn't be an option in geometry nodes, at least for now.
I expect that this type won't be used directly very often, it
should mostly be cast to an enum type. However, with support
for 8 bit integers, it also makes sense to add things like mixing
implementations for consistency.

This callback was only needed to allow specific handling of proxies, now
that theses have been removed the generic
`BKE_lib_id_make_local_generic` code works for objects as well.
Part of T91671.
Not much else to say, this is mainly a massive deletion of code.
Note that a few cleanups possible after this proxy removal were kept out
of this commit to try to reduce a bit its size.

Since f59767ff97, these hair layer types are unused. Since DNA
compatibility was broken with any files that would contain them, the
indices can be reused to avoid growing custom data's typemap.
This patch refactors the "Hair" data-block, which will soon be renamed
to "Curves". The larger change is switching from an array of `HairCurve`
to find indices in the points array to simply storing an array of offsets.
Using a single integer instead of two halves the amount of memory for that
particular array.
Besides that, there are some other changes in this patch:
- Split the data-structure to a separate `CurveGeometry`
DNA struct so it is usable for grease pencil too.
- Update naming to be more aligned with newer code and the style guide.
- Add direct access to some arrays in RNA
-- Radius is now retrieved as a regular attribute in Cycles.
-- `HairPoint` has been renamed to `CurvePoint`
-- `HairCurve` has been renamed to `CurveSlice`
- Add comments to the struct in DNA.
The next steps are renaming `Hair` -> `Curves`, and adding support
for other curve types: Bezier, Poly, and NURBS.

This is partially caused by a stupid mistake in cfa53e0fbe
where I missed initializing the `vert_normals` pointer in
`MResolvePixelData`. It's also caused by questionable assumptions
from DerivedMesh code that vertex normals would be valid.
The fix used here is to create a temporary mesh with the data necessary
to compute vertex normals, and ensure them here. This is used because
normal calculation is only implemented for `Mesh` and edit mesh, not
`DerivedMesh`. While this might not be great for performance, it's
potentially aligned with future refactoring of this code to remove
`DerivedMesh` completely. Since this is one of the last places the data
structure is used, that would be a great improvement.

Iterating over scene's objects while we modify those (through proxy to
override conversion code) is call for problems (use after free etc.).
Instead, all proxy objects need to be gathered first in a temporary
list, and processed all at once in a second loop.
`BKE_collection_object_add` ensures given object is added to an editable
collection, and not e.g. a linked or override one.
However, some processes like do_version manipulate collections also from
libraries, i.e. linked collections, in those cases we need a version of
the code that unconditionnally adds the given object to the given
colleciton.
This is from patch D13988. It removes the "- New" from the menu of the
new obj exporter, changes the default addon to just io_import_obj,
and does the right versioning thing.
Also disables the python tests for the old python exporter.
Those cases are fairly hard to track down... Added some more checks,
also at lower levels, more generic levels of object editing, and fixed
core check in liboverride (previously code was assuming that an override
of a collection only could have overrides of objects or linked objects,
but this is not necessarily true).

Use the ID.recalc flag to detect when updates after frame-change is
needed. Since comparing the last calculated frame doesn't take undo into
account (see code-comment for details).
`ID_RECALC_AUDIO_SEEK` has been renamed to `ID_RECALC_FRAME_CHANGE`
since this is not only related to audio however internally this flag is
still categorized in `NodeType::AUDIO`.

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 will allow to keep the access to deprecated DNA proxy data in that
specific file, instead of allowing deprecated accesses in the whole
override kernel code.
Part of T91671.
Part of the resynching code would access collections' objects base
cache, which can be invalid at that point (due to previous ID remapping
and/or deletion). Use a custom recursive iterator over collections'
objects instead, since those 'raw' data like collection's objects list,
and collection's children lists, should always be valid.
Found while investigating a studio production file.
Mistake in the 974981a637: f the edit data is not present then the
origindex codepath is to be used. Added a brief note about it on the
top of the file.
More ideally would be to remove edit mesh from non-bmesh-wrappers
but this would require changes in the draw manager to make a proper
decision about drawing edit mode overlays.
Now all proxies will always be converted to library overrides. If
conversion fails, they are simply 'disabled'.
This should be the last 'user-visible' step of proxies removal.
Remaining upcoming commits will remove internal ID management, depsgraph
and evaluation code related to proxies.
Also bump the blendfile subversion.

So far linked proxies were just kept as-is, this is no longer an option.
Attempt to convert them into liboverrides as much as possible, though
some cases won't be supported:
- Appending proxies is broken since a long time, so conversion will fail
here as well.
- When linking data, some cases will fail to convert properly. in
particular, if the linked proxy object is not instanced in a scene
(e.g. when linking a collection containing a proxy as an
epty-instanced collection instead of a view-layer-instanced collection).
NOTE: converion when linking/appending is done unconditionnaly, option
to not convert on file load will be removed in next commit anyway.

This will help when dealing with liboverrides from other library files,
e.g for resync or proxies conversion.
This commit only affects proxy conversion.

rB5a9a16334c573c4566dc9b2a314cf0d0ccdcb54f.

From investigating T95185, it's important the normal returned by
SCULPT_vertex_normal_get always match the PBVH normal array.
Since this is always initialized in the PBVH, there is no advantage
in storing the normal array in two places, it only adds the possibility
that changes in the future causing different meshes normals to be used.
