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.
* Replace license text in headers with SPDX identifiers.
* Remove specific license info from outdated readme.txt, instead leave details
to the source files.
* Add list of SPDX license identifiers used, and corresponding license texts.
* Update copyright dates while we're at it.
Ref D14069, T95597
Sometime throughout development some checks got lost during refactor.
This change makes it so that if OIDN is not supported on the current
CPU Cycles will report an error and stop rendering. This behavior is
similar to when an OptiX denoiser is requested and there is no OptiX
compatible device available.
The easiest way to verify this change is to force return false from
the `openimagedenoise_supported()`.
Fixes Cycles part of the T94127.

Remove prefix of filenames that is the same as the folder name. This used
to help when #includes were using individual files, but now they are always
relative to the cycles root directory and so the prefixes are redundant.
For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
* Split render/ into scene/ and session/. The scene/ folder now contains the
scene and its nodes. The session/ folder contains the render session and
associated data structures like drivers and render buffers.
* Move top level kernel headers into new folders kernel/camera/, kernel/film/,
kernel/light/, kernel/sample/, kernel/util/
* Move integrator related kernel headers into kernel/integrator/
* Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/
For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
The thread affinity setting in OIDN can break multithreading on some CPUs.
While this leads to somewhat worse performance on CPUs that do work correctly,
it's better than having some CPUs use only half the cores.
Implement an overscan support for tiles, so that adaptive sampling can
rely on the pixels neighbourhood.

This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

all the changes since intermediate changes would often fail building or tests.
