This patch adds a CMake option "WITH_CYCLES_DEBUG" which builds cycles with
a feature that allows debugging/selecting the direct-light sampling strategy.
The same option may later be used to add other debugging features that could
affect performance in release builds.
The three options are:
* Forward path tracing (e.g., via BSDF or phase function)
* Next-event estimation
* Multiple importance sampling combination of the previous two methods
Such a feature is useful for debugging light different sampling, evaluation,
and pdf methods (e.g., for light sources and BSDFs).

Our CMake setup refuses to run from the source directory (i.e. Blender does
not support in-source builds). Instead, it shows instructions on how to
clean up after an accidental `cmake` invocation. These instructions missed
one directory that should also be removed (`CMakeFiles`), so that's been
added to the message now.
No functional changes to Blender or the build.
This package allows Python scripts to handle compressed blend files (see
rB2ea66af742bc). This is for example needed by Blender Asset Tracer to
send files to a Flamenco render farm.
This change includes a new `WITH_PYTHON_INSTALL_ZSTANDARD` build-time
option, to control whether to actually install the package. For this the
already-existing approach for Requests was copied.

Make building the thumbnail extraction executable optional,

NOTE: this feature is not ready for user testing, and not yet enabled in daily

HIP is a heterogenous compute interface allowing C++ code to be executed on
GPUs similar to CUDA. It is intended to bring back AMD GPU rendering support
on Windows and Linux.

As of the time of writing, it should compile and run on Linux with existing
HIP compilers and driver runtimes. Publicly available compilers and drivers
for Windows will come later.

For Blender.app: dropping libomp.dylib next to Blender executable is
enough for it getting picked up since `@executable_path` is an rpath.
For non-distributed binaries datatoc, makesdna, tests etc, code for
copying libomp.dylib to build folder is removed and replaced by
CMake's rpath option for *build* tree.
For bpy.so, the post build rpath change has also been replaced by CMake
rpath option for *install* tree.
Since -id has been changed in D11748, remove the
`install_name_tool -change ...` command.
Any dylib can just be dropped at `MAC_BLENDER_TARGET_DYLIBS_DIR`

This is causing issues for some users launching Blender, because EGL indirectly

This will replace GLX with EGL for X11. GLEW does not support GLX and EGL
at the same time. Most distributions build GLEW with GLX support, so we
have to use the externally provided GLEW and build with EGL support.
This effectively sets WITH_SYSTEM_GLEW to OFF for all Linux configurations.

WITH_CYCLES_DEBUG was used for rendering BVH debugging passes. But since we
mainly use Embree an OptiX now, this information is no longer important.
WITH_CYCLES_DEBUG_NAN will enable additional checks for NaNs and invalid values
in the kernel, for Cycles developers. Previously these asserts where enabled in
all debug builds, but this is too likely to crash Blender in scenes that render
fine regardless of the NaNs. So this is behind a CMake option now.
Fixes T90240
We were manually setting the compiler flags
for C++17 support for this previously. CMake
can do this for us in a uniform way without
having to worry about compiler specifics.
Setting these flags manually somehow brought
out some unwanted behaviour (CMake switching
back to C++14) in the nightly CMake builds.
Unsure if that's a CMake bug or planned
new behaviour for future version, but best
to play it safe.
These flags are supported since CMake 3.1
so should not break anything.

Technical notes:
* The conversion candidate window is drawn by the input method program calling
`firstRectForCharacterRange`.
* The string before confirmation (called `composite` in blender) is handled in
the `setMarkedText` method called by the input method program.
* The string after confirmation (called `result` in the blender) is processed
in the `insertText` method called by the input method program.

Build System
============
This is an API breaking new version, and the updated code only builds with
OpenColorIO 2.0 and later. Adding backwards compatibility was too complicated.
* Tinyxml was replaced with Expat, adding a new dependency.
* Yaml-cpp is now built as a dependency on Unix, as was already done on Windows.
* Removed currently unused LCMS code.
* Pystring remains built as part of OCIO itself, since it has no good build system.
* Linux and macOS check for the OpenColorIO verison, and disable it if too old.
Ref D10270
Processors and Transforms
=========================
CPU processors now need to be created to do CPU processing. These are cached
internally, but the cache lookup is not fast enough to execute per pixel or
texture sample, so for performance these are now also exposed in the C API.
The C API for transforms will no longer be needed afer all changes, so remove
it to simplify the API and fallback implementation.
Ref D10271
Display Transforms
==================
Needs a bit more manual work constructing the transform. LegacyViewingPipeline
could also have been used, but isn't really any simpler and since it's legacy
we better not rely on it.
We moved more logic into the opencolorio module, to simplify the API. There is
no need to wrap a dozen functions just to be able to do this in C rather than C++.
It's also tightly coupled to the GPU shader logic, and so should be in the same
module.
Ref D10271
GPU Display Shader
==================
To avoid baking exposure and gamma into the GLSL shader and requiring slow
recompiles when tweaking, we manually apply them in the shader. This leads
to some logic duplicaton between the CPU and GPU display processor, but it
seems unavoidable.
Caching was also changed. Previously this was done both on the imbuf and
opencolorio module levels. Now it's all done in the opencolorio module by
simply matching color space names. We no longer use cacheIDs from OpenColorIO
since computing them is expensive, and they are unlikely to match now that
more is baked into the shader code.
Shaders can now use multiple 2D textures, 3D textures and uniforms, rather
than a single 3D texture. So allocating and binding those adds some code.
Color space conversions for blending with overlays is now hardcoded in the
shader. This was using harcoded numbers anyway, if this every becomes a
general OpenColorIO transform it can be changed, but for now there is no
point to add code complexity.
Ref D10273
CIE XYZ
=======
We need standard CIE XYZ values for rendering effects like blackbody emission.
The relation to the scene linear role is based on OpenColorIO configuration.
In OpenColorIO 2.0 configs roles can no longer have the same name as color
spaces, which means our XYZ role and colorspace in the configuration give an
error.
Instead use the new standard aces_interchange role, which relates scene linear
to a known scene referred color space. Compatibility with the old XYZ role is
preserved, if the configuration file has no conflicting names.
Also includes a non-functional change to the configuraton file to use an
XYZ-to-ACES matrix instead of REC709-to-ACES, makes debugging a little easier
since the matrix is the same one we have in the code now and that is also
found easily in the ACES specs.

* USD and OpenVDB headers use deprecated TBB headers, suppress all deprecation
