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.

7e9776a167 Fix #125863: Crash baking textures with Cycles Metal
The issue was caused by an attempt to write buffer pass which is
actually supposed to be calculated as compositing (either summing
direct/indirect lights, optionally diving by albedo).

The fact that the crash was only observed on Metal is a lucky
con-incident: it just happened to be so that writing at offset
-1 to the render buffer did not trigger obvious issues.

79787bf8e1 Cycles: Improve denoiser update performance when rendering with multiple GPUs
This patch causes the render buffers to be copied to the denoiser
device only once before denoising and output/display is then fed
from that single buffer on the denoiser device. That way usually all
but one copy (from all the render devices to the denoiser device)
can be eliminated, provided that the denoiser device is also the
display device (in which case interop is used to update the display).
As such this patch also adds some logic that tries to ensure the
chosen denoiser device is the same as the display device.

d7d40745fa Cycles: changes to source code folders structure
* 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.
