with a very high min-driver version requirement, placeholder until JIT
CentOS runtime compilation issue gets fixed in a defined version.
min-driver version check can be worked around by setting
CYCLES_ONEAPI_ALL_DEVICES environment variable.

Add intern/wayland_dynload which is used when WITH_GHOST_WAYLAND_DYNLOAD
is enabled (off by default). When enabled, systems without Wayland
installed will fall back to X11.
This allows Blender to dynamically load:
- libwayland-client
- libwayland-cursor
- libwayland-egl
- libdecor-0 (when WITH_GHOST_WAYLAND_LIBDECOR is enabled).

This patch adds a new Cycles device with similar functionality to the
existing GPU devices. Kernel compilation and runtime interaction happen
via oneAPI DPC++ compiler and SYCL API.
This implementation is primarly focusing on Intel® Arc™ GPUs and other
future Intel GPUs. The first supported drivers are 101.1660 on Windows
and 22.10.22597 on Linux.
The necessary tools for compilation are:
- A SYCL compiler such as oneAPI DPC++ compiler or
https://github.com/intel/llvm
- Intel® oneAPI Level Zero which is used for low level device queries:
https://github.com/oneapi-src/level-zero
- To optionally generate prebuilt graphics binaries: Intel® Graphics
Compiler All are included in Linux precompiled libraries on svn:
https://svn.blender.org/svnroot/bf-blender/trunk/lib The same goes for
Windows precompiled binaries but for the graphics compiler, available
as "Intel® Graphics Offline Compiler for OpenCL™ Code" from
https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html,
for which path can be set as OCLOC_INSTALL_DIR.
Being based on the open SYCL standard, this implementation could also be
extended to run on other compatible non-Intel hardware in the future.

GLEW does not support GLX and EGL at the same time, and the distribution version
is likely to have GLX.
This also refactors the code so all OpenGL related CMake options are together.

Add WITH_GHOST_WAYLAND_DBUS option, so Blender can be built without
DBUS support. Currently it's only used to access the cursor theme.
Without this the "default" cursors are used instead.
Disabling this since it adds an additional dependency for a minor gain
in functionality, with the benefit of removing a library requirement.
There is also a problem where Blender hangs on startup for ~5 seconds
when DBUS isn't running. Eventually it would be good to be able to avoid
this problem without a build option.

This implements client-side window decorations for moving and resizing
windows and HiDPI support.
This functionality depends on the external project 'libdecor' that is
currently a build option: WITH_GHOST_WAYLAND_LIBDECOR.

The following CMake options have been added (enabled by default),
except for the lite build configuration.
- WITH_IO_STL
- WITH_IO_WAVEFRONT_OBJ
- WITH_IO_GPENCIL (for grease pencil SVG importing).
Note that it was already possible to disable grease pencil export
by disabling WITH_PUGIXML & WITH_HARU.
This is intended to keep the lite builds fast and small for building,
linking & execution.

It can be assumed that all scripts comply with basic pep8 formatting
regarding white-space, indentation etc.
Also remove note in best practices page & update `tests/python/pep8.py`.
If we want to exclude some scripts from make format,
this can be done by adding them to `ignore_files` in:
source/tools/utils_maintenance/autopep8_format_paths.py
Or using `# nopep8` for to ignore for individual lines.

When building blender as a python module, such as for inclusion in a
wheel, it is not permitted to link against python libraries.
This diff does so by simply unsetting the library when building blender
as a python module, instead of the more heavyweight solution of
switching to the cmake FindPython module.

Adds support for linking with some of the dependencies of a USD
build instead of the precompiled libraries from Blender, specifically
OpenSubdiv, OpenVDB and TBB. Other dependencies keep using the
precompiled libraries from Blender, since they are linked statically
anyway so it does't matter as much. Plus they have interdependencies
that are difficult to resolve when only using selected libraries from
the USD build and can't simply assume that USD was built with all
of them.
This patch also makes building the Hydra render delegate via the
standalone repository work and fixes various small issues I ran into
in general on Windows (e.g. the use of both fixed paths and
`find_package` did not seem to work correctly). Building both the
standalone Cycles application and the Hydra render delegate at the
same time is supported now as well (the paths in the USD plugin JSON
file are updated accordingly).
All that needs to be done now to build is to specify a `PXR_ROOT`
or `USD_ROOT` CMake variable pointing to the USD installation,
everything else is taken care of automatically (CMake targets are
loaded from the `pxrTargets.cmake` of USD and linked into the
render delegate and OpenSubdiv, OpenVDB and TBB are replaced
with those from USD when they exist).

Currently only supports single image frames (no animation possible).
If quality slider is set to 100 then lossless compression will be used,
otherwise lossy compression is used.
Gives about 35% reduction of filesize save when re-saving splash screens with lossless
compression.
Also saves much faster, up to 15x faster than PNG with a better compression ratio as a plus.
Note, this is currently left disabled until we have WebP libs (see T95206)

rBc1909770e7f192574ea62449dd14b4254637e604 introduced "PXR_LIB_PREFIX" for building the
dependencies, so only makes sense to use the same name in the Hydra render delegate CMake too

This patch adds a Hydra render delegate to Cycles, allowing Cycles to be used for rendering
in applications that provide a Hydra viewport. The implementation was written from scratch
against Cycles X, for integration into the Blender repository to make it possible to continue
developing it in step with the rest of Cycles. For this purpose it follows the style of the rest of
the Cycles code and can be built with a CMake option
(`WITH_CYCLES_HYDRA_RENDER_DELEGATE=1`) similar to the existing standalone version
of Cycles.
Since Hydra render delegates need to be built against the exact USD version and other
dependencies as the target application is using, this is intended to be built separate from
Blender (`WITH_BLENDER=0` CMake option) and with support for library versions different
from what Blender is using. As such the CMake build scripts for Windows had to be modified
slightly, so that the Cycles Hydra render delegate can e.g. be built with MSVC 2017 again
even though Blender requires MSVC 2019 now, and it's possible to specify custom paths to
the USD SDK etc. The codebase supports building against the latest USD release 22.03 and all
the way back to USD 20.08 (with some limitations).

Since USD 21.11 the libraries are prefixed with "usd_", i.e.
"libusd_m.a" became "libusd_usd_m.a". This commit adjusts our
`usd.cmake` (for building USD) and `FindUSD.cmake` (for finding the USD
libraries) so that they work with and without this `usd_` prefix.
