This continues the cmake modernization effort and introduces support for
allowing our optional dependencies to integrate properly. TBB is added
here as it's proven troublesome to maintain correctly.
Currently the only Blender project which uses the TBB headers directly
is `blenlib`. However, all downstream projects which require blenlib as
their dependency, and wish to properly make use of its threading
facilities, needed to define various TBB items in their CMake files. Not
only is this unnecessary and arcane, but several projects didn't do this
and ended up not using threading as well as producing ODR violations
along the way[1].
This PR makes TBB a modern dependency and exposes it PUBLIC'ly from
`blenlib`. All downstream projects which depend on blenlib will now
receive everything they require from TBB automatically. This includes
the `WITH_TBB` define, the headers, and the library itself.

When having several clang versions installed cmake would default
to the last llvm directory in the registry when finding the openmp
libraries. Two problems with that are :
1- The registry entry may not exist
2- Even if it exists it may not point to the right folder for the
Current compiler.
This PR changes the behaviour to look relative to the clang binary
to find the openmp libraries.

It allows to more easily override cmake options which we want to
be enabled on the buildbot.
In a way it was possible to do via the pipeline config, but this
change provides a more natural way for Blender developers to set
CMake configuration which is to be enabled on buildbot, but not
on local developer machines.

Fribidi uses Meson, which auto-detects presence of ccache and uses it
when found. This could cause incorrect compilation results when doing
a cross-compilation to different platforms on the same machine.
Pass the typical configuration environment to the Meson setup, which
takes care of specifying deployment targets and architecture as the
compiler flags, preventing ccache from using result from a different
architecture.
This is similar to the Meson setup used for Harfbuzz and Epoxy.

We've seen a ~15% performance regression on Meteor Lake iGPUs since
17f2cdd104, this new compiler version
restores it.
No need to bump the minimum supported driver version as it was already
at 101.5518.

* Always define root directories in LIBDIR even when not needed,
to silence some warnings.
* Only show warnings about not finding libs when oneAPI is enabled.
* Prefix message for context.
The resulting .pyd files for a debug build had wrong filenames.
MaterialX and OpenImageio used incorrect soabi tags, while usd
had a double _d_d postfix.
These changes should not affect linux+mac
autopep8_format_paths.py was never wired up in the windows tooling,
this PR wires it up, to get around a 8191 limitation for command
lines on windows an alternative "--no-subprocess" option has been
introduced to call the pep8 module directly from python.
TODO: A subprocess is still used for getting the version information
Contributors:
- @campbellbarton fixes to autopep8_format_paths.py to support
the -no-subprocess option.
