c87a269021 Fix #133953: Cycles oneAPI texture randomly renders black
* Do oneAPI copy optimization as part of host memory alloc and free, so
  it is properly released before host memory is freed.
* Synchronize after loading texture info, like CUDA and HIP.

f99f958c47 Refactor: Cycles: Add host_alloc/free to device API
This may be used for device to do host memory allocation in a way that
is more efficient for copy the host memory to the device.

Also rename and group device memory allocation functions for clarity.

2cfe2e0bfe Fix: Cycles: Re-copy memory from host to device without realloc
Should be a bit more efficient, and it fixes host memory fallback bugs,
where host memory was incorrectly freed during re-copy. For the case
where memory should get reallocated on the host, a new mem_move_to_host
was added.

Thanks to Jorn Visser for investigating and finding this problem.

b803d7fabb Fix: Command line Cycles render crash on multi-CUDA device
Since #118841 there are more cases where Cycles would check for the
graphics interop support. This could lead to a crash when graphics
interop functions are called without having active graphics context.

This change makes it so there is no graphics interop calls when doing
headless render. In order to achieve this the device creation is now
aware of the headless mode.

759bb6c768 Cycles: oneAPI: Enable host memory migration
This enables scenes with all textures not fitting in GPU
memory to finally render. For scenes that are fitting,
no functional change or performance change is expected.

26c93c8359 Cycles: Enable OIDN 2.3 lazy device module loading
This enables the new lazy module loading behavior introduced in OIDN 2.3,
without breaking compatibility with older versions of OIDN (using separate
code paths).

Also, the detection of OIDN support for devices is now much cleaner, and
devices do not need to be matched by PCI address or device name anymore.

8a6f7640d6 Cycles: Make OIDN on GPU use the existing SYCL queue
There's already a queue from the Cycles rendering device, so let OIDN use the same instead of creating a new one.

d8e8e8eb9a Cycles: oneAPI: fix device compilation with latest MSVC
<algorithm> header include is missing from some sycl headers, this will
be fixed upstream with https://github.com/intel/llvm/pull/10424,
meanwhile, we work around it by including it directly.

3f8c995109 Cycles: add hardware raytracing support to oneAPI device
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.

7eeeaec6da Cycles: use direct linking for oneAPI backend
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.

a02992f131 Cycles: Add support for rendering on Intel GPUs using oneAPI
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.
