OpenImageDenoise V2 comes with GPU support for various backends. This adds a new class, OIDNDenoiserGPU, in order to add this functionality into the existing Cycles post processing pipeline without having to change it much. OptiX and OIDN CPU denoising remain as they are. Rendering on a supported Intel GPU will automatically select the GPU denoiser.
Device support is initially limited to the oneAPI devices that are supported by Cycles, but can be extended.

Recent versions of DPC++ dropped using the environment variable
SYCL_PI_LEVEL_ZERO_USE_COPY_ENGINE_FOR_IN_ORDER_QUEUE=0 we were setting.
We're now also setting SYCL_PI_LEVEL_ZERO_USE_COPY_ENGINE=0 by default
to keep a consistent behavior.
Updated Embree 4 library with GPU support is required for it to be
compiled - compatiblity with Embree 3 and Embree 4 without GPU support
is maintained.
Enabling hardware raytracing is an opt-in user setting for now.

This is a minimal set of changes, allowing a lot of cleanup that can
happen afterward as it allows sycl method and objects to be used outside
of kernel.cpp.

Additionally, just stick to a pure error stating. Such messages
are aimed for developers and it is rather implied that oneAPI
rendering will be disabled.
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.
