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.

Currently on Windows some dependencies are built with MinGW/GCC 3.x
this commit removes that, in favor of building them with MSVC
via msys2. This will make it easier in the future to offer Win/Arm64
builds of blender.
Notable changes:
- This change drops support for the external libxvid library in favor
of ffmpegs built in support for this format. This has been done with
permission from the VFX module.

This reverts commit 451751380c.
Seems like this broke linux/mac, likely needs to detect of libxvid
is there or not. For now revert until we sort this out.

THis is bumping dependencies to fix known CVEs, with the exception of
OpenImageIO which also includes bugfixes for performance and correctness
with some image types.
zlib 1.2.12 -> 1.2.13
freetype 2.11.1 -> 2.12.1
openimageio 2.3.13.0 -> 2.3.20.0
python 3.10.2 -> 3.10.8
openjpeg 2.4.0 -> 2.5.0
ffmpeg 5.0 -> 5.1.2
sndfile 1.0.28 -> 1.1.0
xml2 2.9.10 -> 2.10.3
expat 2.4.4 -> 2.4.9
openssl 1.1.1g/i -> 1.1.1q
sqlite 3.31.1 -> 3.37.2
Notable changes:
* AOM: the hack we had in place to make it not detect pthreads on windows no
longer worked with a more recent cmake version. Disabled pthreads with a
diff on Windows.
* Python: embedded copy of zlib 2.1.12 swapped out for our 2.1.13 copy with
some folder manipulation on Windows.
* Freetype: was harbouring a copy of zlib 2.1.12 as well, so that had to end.
* FFmpeg: patch used to fix D11796 is no longer needed. Add new patch to deal
with simple_idct.asm generating an object file with no sections in it,
backport from upstream commit.
* TinyXML: still being downloaded but no longer used by OpenColorIO, removed.
* GMP applied upstream patch to fix CVE-2021-43618, as there is no release yet.
* SQLite and Libsndfile patches no longer needed.

The previous 3.1 libraries (accidentally) used glApi instead of GLEW and were
working for GPU subdivision, so revert to that. There's a suspected conflict
with Blender's own bundled GLEW or other issue with GLEW, causing the crash in
T97737.
The current GPU subdivision implementation does not need OpenCL, CUDA or GLFW.
So also remove libraries needed for that. It's simpler to stick to compute
shaders in OpenGL/Vulkan/Metal and not involve additional APIs.

This aligns with the VFX reference platform 2020 along with the decision
to stick to Python 3.7, see T68774.
Blosc was downgraded to 1.5 as recommended by the OpenVDB documentation.
IlmBase and OpenEXR are now built together with CMake rather separately
using autoconf.
