dd51c8660b Refactor: Cycles: Add const keyword where possible, using clang-tidy
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.

9e267bbd57 Cycles: Use denoising device info to pick automatic denoiser
Ever since the introduction of GPU OIDN denoising on CPU devices,
using the path_tracing_device info to pick the automatic denoiser has
typically led to incorrect results.

This commit fixes this issue by using the denoising device info to pick
the denoiser.

c9c777ddaa Fix #70114: Cycles: Particle systems missing in headless multiview render
The problem here was that `free_data_after_sync` frees the particle cache in headless or locked-UI mode, but the second view doesn't regenerate them.

For multi-view renders, dropping caches is a tradeoff between compute and memory - dropping allows to reduce peak memory usage, but requires recomputation for the next view. With the current design however, dropping is not something that is easily achievable anyways (see the referenced bugs). So until something more reliable and better fitting is implemented, keep the data from Blender side until the last view.

Since `free_data_after_sync` doesn't do anything for baking or viewport renders anyways, it's easiest to just move this out into `BlenderSession::render` since that already checks whether another view is still outstanding.

Also fixes #73221 and #107589.

71253e1bb0 Fix Cycles baking forcing denoising of combined pass
This is mistake in the PR #117483

Simple solution: make the pass configuration logic to only disable
denoising, and never allow to enable it.

6f681105ec Cycles: Skip denoising during bake when pass does not support denoising
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.

eb8d56328d Cycles: Disable unused closure types when baking a specific component
When baking e.g. the Diffuse pass, use the existing filter logic to
disable glossy and transmission closures.

This reduces baking time and noise when baking individual components

078b2d7174 Fix #107777: Cycles baking of Shadow not working anymore
After the removal of the Shadow pass this no longer worked. Now it works by
marking the object as a shadow catcher and returning the Shadow Catcher pass.

The result is different than before, since it also takes into account indirect
light now and uses a different method to weight the contribution of lights that
is adaptive to the light strength.

0731d78d00 Cycles: remove shadow pass
This was not working well in non-trivial scenes before the light tree, and now
it is even harder to make it work well with the light tree. It would average the
with equal weight for every light object regardless of intensity or distance, and
be quite noisy due to not working with multiple importance sampling.

We may restore this if were enough good use cases for the previous implementation,
but let's wait and see what the feedback is.

Some uses cases for this have been replaced by the shadow catcher passes, which
did not exist when this was added.

b9998541e1 Fix part of T100626: Cycles not using tiles for baking
Leading to excessive memory usage compared to Blender 2.93. There's still
some avoidable memory usage remaining, due to the full float buffer in the
new image editor drawing and not loading the cached EXR from disk in tiles.

Main difficulty was handling multi-image baking and disk caches, which is
solved by associating a unique layer name with each image so it can be
matched when reading back the image from the disk.

Also some minor header changes to be able to use RE_MAXNAME in RE_bake.h.

When new display driver is given to the PathTrace ensure that there are
no GPU resources used from it by the work. This solves graphics interop
descriptors leak.

20cb2c72a5 Fix second render failure with Cycles persistent data
The issue was caused by the recent changes in the way how the
render result is drawn: the display driver now could hold an
OpenGL resources. Those resources are not shared across contexts
so whenever OpenGL context is destroyed those resources are to
be destroyed as well (and not attempted to be re-used for a next
render).

Do such destruction and entire driver re-creation since it does
simplifies things from API usage point of view without causing
measurable slowdown.

Steps to reproduce the issue:
- Set the render resolution to 2x of Full HD
- Enable persistent data
- Render (F12)
- Render again

Observe OpenGL state being corrupted. Easy to see in debug mode
where IMM abstraction level reports issues about the buffer size
not being the proper size. This was caused by the display driver
trying to use VAO from the previous OpenGL context.

fd25e883e2 Cycles: remove prefix from source code file names
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.
