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.

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.

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.

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.
The pre-4.0 Principled BSDF had a special diffuse BSDF that contained
the roughness value from the node. Since 4.0, the regular Diffuse BSDF is used,
so we need to ignore it when determining the roughness value for baking.
The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

Fixes an issue where CPU specific render settings (e.g. path guiding)
would be hidden when GPU Compute has been selected for rendering,
but a GPU hasn't been selected in preferences.

In this case the object transform can use more motion steps, but the
geometry needs to have its motion steps fixed since the velocity
attribute completely overrides them.
There was one functional issue with the previous API which was its
use in `VolumeGrid<T>::grid_for_write(tree_token)`. The issue was
that the tree token had to be received before the grid is accessed.
However, this `grid_for_write` method might create a copy of the
`VolumeGridData` internally and if it does, the passed in `tree_token`
corresponds to the wrong tree.
The solution is to output the token as part of the method. This has two
additional benefits:
* The API is more safe, because one can't pass an r-value into the methods
anymore. This generally shouldn't be done, because the token should
live at least as long as the OpenVDB tree is used and shouldn't be freed
immediatly.
* The API is a bit simpler, because it's not necessary to call the
`VolumeGrid.tree_access_token()` method anymore.
When a mesh light is shadow-linked to something with a specific
shader network it was possible that the emission_sd_storage was
not bit enough for sampling.
The shade_dedicate_light kernel only evaluates emission of either
light or mesh emitter and then resumes the regular path tracer.
There is no need to store closures.
This change makes it so a smaller storage is used, and also
passes flag to the shader evaluation function indicating that
closures are not to be stored.
