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.

use available `film_pass_pixel_render_buffer()` to access the pointer
to the render buffer.
For shadow state, a similar function `film_pass_pixel_render_buffer_shadow()`
is created, because `shadow_path` instead of `path` is needed.
The enumerator values for various GPU compute platforms were
added starting with OIDN 2.0, with the Metal GPU type added
in OIDN 2.2.
This is an alternative fix to ebb781675d, which does not lead to
unhandled cases in switch statement, and follows the configuration
of OIDN and not Cycles (as OIDN might report devices which are
disabled in local Cycles build).

- Incorrect accurate prefiltering of albedo and normal (lower than expected quality)
- Changing the prefiltering mode has no immediate effect
- Default memory limit is too high (more than OIDN default)
- Memory limit is applied only to the main filter
- Quality setting applied only to the main filter

OpenImageDenoise API exposes two modes, high quality and balanced.
This currently only has effect on Nvidia devices, on which it
provides a noticeable performance improvement without visible
difference in quality. This change sets quality to balanced for
the viewport, and high quality for final frame rendering, as
it's what makes the most sense.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
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.

The last good commit was 8474716abb.
After this commits from main were pushed to blender-v4.0-release. These are
being reverted.
Commits a4880576dc from to b26f176d1a that happend afterwards were meant for
4.0, and their contents is preserved.
In the commonly used cycles headers, it's enough to include
much smaller <iosfwd> than the full <iostream>. While looking at it,
removed inclusion of some other headers from commonly used headers,
that seemed to not be needed.
