Brecht Van Lommel 1ea89c82d4 Build: Remove OpenMP
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.

# Installation Configuration.
#
# NOTE: `WITH_INSTALL_PORTABLE` always defaults to ON when building as a Python module and
# isn't set here as it makes changing the setting impractical.
# Python-developers could prefer either ON/OFF depending on their usage:
#
# - When using the system's Python, disabling will install into their `site-packages`,
# allowing them to run Python from any directory and `import bpy`.
# - When using Blender's bundled Python in `./../lib/` it will install there
# which isn't especially useful as it requires running Python from this directory too.
#
# So default `WITH_INSTALL_PORTABLE` to ON, and developers who don't use Python from `./../lib/`
# can disable it if they wish to install into their systems Python.
# There is no point in copying python into Python.
