This follows the other CMake "modernization" commits, this time for
`bf_intern_openvdb` and the OpenVDB dependency itself.
The difference with this one is that `intern/openvdb` becomes an
"optional" dependency itself. This is because downstream consumers often
want to include this dependency rather than openvdb directly, so this
target must also be optional. Optional, in this case, means the target
always exists but may be entirely empty.
Summary
- If you are using BKE APIs to access openvdb features, then use the
`bf::blenkernel` target
- If you are only using `intern/openvdb` APIs then use the
`bf::intern::optional::openvdb` target (rare)
- For all other cases, use the `bf::dependencies::optional::openvdb`
target (rare)

This change introduces time stretching and pitch scaling.
However, none of this will be compiled at the moment, as rubberband
needs to be added to the dependencies first.

* Add own simple logging system to replace glog, which is no longer
maintained by Google.
* When building in Blender, integrate with CLOG and print all messages
through that system instead.
* --log cycles now replaces --debug-cycles. The latter still works but
is no longer documented.

If an OpenVDB grid has an 8x8x8 block with the same value, it is stored as
a tile with a single value. Now iterate over the bounding box and copy the
value to all voxels for this case.

Almost all content in the libdir we can regenerate, wintab however
is not one of them, and if you generate a new lib folder it's one
of the things you have to manually copy back into place.
this PR moves it out of the libdir and into /extern

- Update to latest ufbx version that adds support for FullWeights
- Handle that in the same way as the Python importer did
- Add test files from ufbx test suite

Now results are similar under different time steps. Additionally it is
now working correctly with different time scale, where smoke lifetime
is proportional to time scale.

Fixes#135897 by introducing a mixing thread to coreaudio, making the callback lock free. At the same time these changes unify all devices that use a mixing thread (now that's jack, pulse, pipewire and coreaudio).

Adds a C++ based FBX importer, using 3rd party ufbx library (design task:
#131304). The old Python based importer is still there; the new one is marked
as "(experimental)" in the menu item. Drag-and-drop uses the old Python
importer; the new one is only in the menu item.
The new importer is generally 2x-5x faster than the old one, and often uses
less memory too. There's potential to make it several times faster still.
- ASCII FBX files are supported now
- Binary FBX files older than 7.1 (SDK 2012) version are supported now
- Better handling of "geometric transform" (common in 3dsmax), manifesting
as wrong rotation for some objects when in a hierarchy (e.g. #131172)
- Some FBX files that the old importer was failing to read are supported now
(e.g. cases 47344, 134983)
- Materials import more shader parameters (IOR, diffuse roughness,
anisotropy, subsurface, transmission, coat, sheen, thin film) and shader
models (e.g. OpenPBR or glTF2 materials from 3dsmax imports much better)
- Importer now creates layered/slotted animation actions. Each "take" inside
FBX file creates one action, and animated object within it gets a slot.
- Materials that use the same texture several times no longer create
duplicate images; the same image is used
- Material diffuse color animations were imported, but they only animated
the viewport color. Now they also animate the nodetree base color too.
- "Ignore Leaf Bones" option no longer ignores leaf bones that are actually
skinned to some parts of the mesh.
- Previous importer was creating orphan invisible Camera data objects for
some files (mostly from MotionBuilder?), new one properly creates these
cameras.
Import settings that existed in Python importer, but are NOT DONE in the new
one (mostly because not sure if they are useful, and no one asked for them
from feedback yet):
- Manual Orientation & Forward/Up Axis: not sure if actually useful. FBX
file itself specifies the axes fairly clearly. USD/glTF/Alembic also do
not have settings to override them.
- Use Pre/Post Rotation (defaults on): feels like it should just always be
on. ufbx handles that internally.
- Apply Transform (defaults off, warning icon): not sure if needed at all.
- Decal Offset: Cycles specific. None of other importers have it.
- Automatic Bone Orientation (defaults off): feels like current behavior
(either on or off) often produces "nonsensical bones" where bone direction
does not go towards the children with either setting. There are discussions
within I/O and Animation modules about different ways of bone
visualizations and/or different bone length axes, that would solve this
in general.
- Force Connect Children (defaults off): not sure when that would be useful.
On several animated armatures I tried, it turns armature animation
into garbage.
- Primary/Secondary Bone Axis: again not sure when would be useful.
Importer UI screenshots, performance benchmark details and TODOs for later
work are in the PR.

It's better for performance to use a single thread pool for all areas of
Blender, and this gets us closer to that.
Bullet, Quadriflow, Mantaflow and Ceres still contain OpenMP code, but it
was already disabled.
On macOS, our OpenMP libraries are no longer compatible with the latest
Xcode 16.3. By removing OpenMP we no longer have to solve that problem.
OpenMP was disabled for bpy module builds on Windows ARM64, which also no
longer needs to be solved.

Only the parallel sparse matrix code was updated. This is used by e.g.
LSCM and ABF unwrap, and performance seems about the same or better.
Parallel GEMM (dense matrix-matrix multiplication) is used by libmv,
for example in libmv_keyframe_selection_test for a 54 x 54 matrix.
However it appears to harm performance, removing parallelization makes
that test run 5x faster on a Apple M3 Max.
There has been no new Eigen release since 2021, however there is active
development in master and it includes support for a C++ thread pool for
GEMM. So we could upgrade, but the algorithm remains the same and
looking at the implementation it just does not seem designed for modern
many core CPUs. Unless the matrix is much larger, there's too much thread
synchronization overhead. So it does not seem useful to enable that
thread pool for us.

To make adding a dependeny on TBB easier.

Removes the playback handle from the synchronizer API and integrates it
into the device, removing the ISynchronizer interface completely.
This has been discussed in more detail in #126047 and its main purpose is to unify the handling of synchronizer events, especially seek which needed different logic for jack vs other backends.
OpenAL now needs a silence playback handle for synchronization but all
other backends are pretty straightforward just counting the mixed
samples in the SoftwareDevice with some specializations for specific
backends that had their own synchronizers before.
Note: CoreAudio changes are untested as I don't have a Mac.

Seems like ASAN has been broken on debug builds for MSVC ever since
d5e50460e7 (1.5 years ago) the core reason is it's incompatible with
fastlink, it'll appear to work, but in the asan reports no symbols
will be resolved.
While looking into this, some other problems like the symbol format being
not inline with the table in the comment above it, and a warning coming
out of /extern were noted.
All of these issues are addressed in this commit.
This change brings the following improvements on the user level
- Support of GPUs with gfx12 architecture
- New HIP-RT library which in addition to the gfx12 support brings
various bug-fixes.
The known limitation of gfx12 is that OpenImageDenoiser does not yet
support this GPU architecture. This means that while Cycles will use the
full advantage of the gfx12 (including hardware accelerated ray-tracing),
denoising will only be possible on CPU, or secondary gfx11 or below GPU.
This is something that requires a change in OIDN and it is to late to do
it for Blender 4.4, but it is something to look forward for Blender 4.5.
The gfx12 changes for the pre-compiled kernels is rather trivial,
so it comes together (in the same PR) as the bigger HIP-RT change.
On the development side this change brings the following improvements:
- One step compile and link (much simpler CMake rules)
- Embedding BVH binaries in hiprt dll (which makes it easier to package
and load, without relying on special path configuration)

In contrast to libamdhip64, for which blender searches in multiple directories,
libhiprt64 only had limited support for non-standard installation directories.
With this commit, the library lookup for HIPRT is handled in a similar way in
the original HIP/ROCm module. This also fixes issues for downstream Linux
distributions where HIPRT support was enabled during build time but was not
available at runtime.
