If one of the devices already used host happed memory but another not,
it would previously realloc both.
Thanks to Jorn Visser for investigating and finding this problem.

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.

Check was misc-const-correctness, combined with readability-isolate-declaration
as suggested by the docs.
Temporarily clang-format "QualifierAlignment: Left" was used to get consistency
with the prevailing order of keywords.

Previously, in case of a failure during BVH transfer, when running out
of memory for example, we could get an error such as "BVH failed to
migrate to the GPU due to Embree library error (no error)", because
embree error status was actually reset before being queried.
This commit fixes its propagation.

IGC 1.0.17384, ocloc 24.31.30508, which:
- add support for Battlemage and Lunar Lake GPUs
- recover from recent performance regression on Linux
- allow to drop older work-around
(9d5164d472) and need for a patched
version on Windows
- ocloc now needs "dg2,mtl" naming for fat binaries.
opencl-clang patches don't get applied anymore by igc build scripts
when llvm is not a git repository, hence I could also drop we can drop
current patch disabling patching.
I've only slightly pushed min-driver-version updates after carefull
testing, instead of jumping to the same version as ocloc as we use to.

This new version of the graphics compiler solves a performance
regression on Arc, adds support for Battlemage and Lunar Lake GPUs, and
allows to drop older patch to build fat binaries with broad
compatibility.
This latter change requires using -device dg2,mtl naming instead of
passing architecture ids.

Embree device pointer can end up being nullptr even when Embree on GPU is
expected to be used. Previous implementation overlooked this possibility,
leading to a completely silent fallback to the non-Hardware ray-tracing path,
this commit fixes it. We've noticed this as now Embree relies on a driver
component: https://github.com/intel/level-zero-raytracing-support that can
potentially be missing from a system.

SYCL runtime currently relies on an internal driver behavior that will
break the driver version string returned by SYCL if it changes:
https://github.com/oneapi-src/unified-runtime/issues/1777
This will be fixed at SYCL runtime level but until we use a new enough
one, we need to add additional verifications to avoid blocking execution
on a driver that will change this internal behavior.

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.

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.

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.

With drivers 101.4972 to 101.5085, some Arc and Meteor Lake devices
ignore the prebuilt GPU binaries and since the addition of Meteor Lake
binaries, fail caching newly generated ones on Windows.
This got fixed in drivers 101.5186 so it's preferable to require these
new drivers to be used.
NDEBUG is part of the C standard and disables asserts. Only this will
now be used to decide if asserts are enabled.
DEBUG was a Blender specific define, that has now been removed.
_DEBUG is a Visual Studio define for builds in Debug configuration.
Blender defines this for all platforms. This is still used in a few
places in the draw code, and in external libraries Bullet and Mantaflow.

In order to speedup compilation, we upgrade IGC to 1.0.14828.26 along
with ocloc and the associated dependencies.
We also bump min-driver version accordingly to 26918.
Ref !114341
The first public Windows driver version with a higher number is
101.4824, so we bump the min-required driver version on Windows to this
one to ensure compatibility.
During recent testing, the oldest 101.4032 (windows) and <25812 (linux)
drivers led to crashes during JIT compilation, so we bump the
requirement to newer 101.4313 and 25812.14 drivers that do incorporate
the required fixes.

Only Embree CPU BVH was built in the multi-device case. However, one
Embree GPU BVH is needed per GPU, so we now reuse the same logic as in
the other backends.
