Turns out we were not building OSL with OptiX enabled anymore.
Also check now if the OSL builds has OptiX support and if not
disable it in Cycles.
Building OSL with support for this (still) does not require
either the OptiX SDK or CUDA, it only needs LLVM.

Add new "Soft Falloff" option on point and spot light that uses
the old light behavior from Blender versions before 4.0. Blend
files saved with those older versions will use the option.
This option is enabled by default on new lights.

- 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.

HWRT checkboxes visibility in the Cycles settings wasn't uniform across devices.
With this change, we unify it and gray out these in case HWRT isn't available.

- "can not" -> "cannot" in many places (ambiguous, also see
Writing Style guide).
- "Bezier" -> "Bézier": proper spelling of the eponym.
- Tool keymaps: make "Uv" all caps.
- "FFMPEG" -> "FFmpeg" (official spelling)
- Use MULTIPLICATION SIGN U+00D7 instead of MULTIPLICATION X U+2715.
- "LClick" -> "LMB", "RClick" -> "RMB": this convention is used
everywhere else.
- "Save rendered the image..." -> "Save the rendered image...": typo.
- "Preserve Current retiming": title case for property.
- Bend status message: punctuation.
- "... class used to define the panel" -> "header": copy-paste error.
- "... class used to define the menu" -> "asset": copy-paste error.
- "Lights user to display objects..." -> "Lights used...": typo.
- "-setaudio require one argument" -> "requires": typo.

This is a leftover from when there was a global option for transparent
shadows, but since it's now per material this makes no sense anymore.
Solution found by Olivier Maury.

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.
This allows users to turn off reflective and refractive caustics
separately from each other when using the Generalized Schlick material.
This will impact the Principled BSDF and Glass BSDF, along with some
custom OSL scripts.

Wayland, macOS & SDL weren't using the start-time of the process.
The start-time offset isn't needed so it's similar to forward the
systems method of accessing the time in milliseconds.
Seems to be a fairly niche type, but some people (apparently mostly in the automotive space) use it.
Also improves the handling of IES files in general and lets Cycles accept IES files that are technically violating the spec - which seems to be most of them...

Improve the handling of Principled BSDF Caustics from Metallic
and Transmissive components, improving consistency between SVM and OSL,
and offering more predictable results.

While investigating Blender compilation time for windows-arm64, we
identified two compilation units that were taking a long time to compile
(~1h each). This affects windows-x64 builds as well.

This changes fixes the slowdown when baking data passes like Normal with
the denoiser enabled on scene settings.
When baking to 4K textures denoising could take considerable amount of
time, which is better be avoided.

Cycles can use a per face flag to determine if a face is smooth or flat,
and there is no need to use corner normals in such cases. So revert to
not doing that as before, which also saves a bit of memory.
There is a pre-existing issue where faces are split by sharp edges and
autosmooth, which is not solved by this. It's only fixing the regression.
