This helps avoid out of memory errors for complex scenes, and improves
performance for smaller scenes with more memory available for states.
Metal already had logic like this, now the logic is centralized and can
be used for all GPU backends.
The parameters have been somewhat tuned per device, based on earlier
work for oneAPI in #163437 and CUDA in #163532. For Metal the behavior
should remain basically the same.
For oneAPI, this enables free_memory queries on iGPUs, as driver have
been exposing this for some time.

Pull Request: https://projects.blender.org/blender/blender/pulls/163930
When verbose level 4 is enabled, Blender prints kernel performance
data for Cycles on GPU backends (except Metal that doesn't use
debug_enqueue_* methods) for groups of kernels.
These changes introduce a new CYCLES_DEBUG_PER_KERNEL_PERFORMANCE
environment variable to allow getting timings for each kernels
separately and not grouped with others. This is done by adding
explicit synchronization after each kernel execution.

* 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* Remove specific license info from outdated readme.txt, instead leave details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
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.
