New ("fullframe") CPU compositor backend is being used now, and all the code
related to "tiled" CPU compositor is just never used anymore. The new backend
is faster, uses less memory, better matches GPU compositor, etc.
TL;DR: 20 thousand lines of code gone.
This commit:
- Removes various bits and pieces related to "tiled" compositor (execution
groups, one-pixel-at-a-time node processing, read/write buffer operations
related to node execution groups).
- "GPU" (OpenCL) execution device, that was only used by several nodes of
the tiled compositor.
- With that, remove CLEW external library too, since nothing within Blender
uses OpenCL directly anymore.

The CPU compositor always adds a filter for normal and albedo even if
they don't contain any data, that is, when they are not connected to
anything, by inflating a buffer with the editor value, which is not even
accesible to the user. In anycase, such a solid color will not help do
anything in the denoise operation.
This patch aligns the implementation by only adding the abeldo and
normal filter if they contain actual data, speeding up the operation in
the process.

This change makes it so the OIDN is listening to the node execution
being cancelled, allowing for a more instant user feedback on the
compositor graph changes. It is especially visible when dealing with
4k images, and using pre-filter on the guiding passes.
Similar implementation to what Cycles does.
This change covers tiles and full-frame compositors.
The GPU compositor needs extra work to have this supported.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
For example
```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```
becomes
```
OIIOOutputDriver::~OIIOOutputDriver() {}
```
Saves quite some vertical space, which is especially handy for
constructors.

This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
Push the const usage a bit further for compositor nodes, so that they
are more explicit about not modifying original nodes from the editor.

Use a shorter/simpler license convention, stops the header taking so
much space.
Follow the SPDX license specification: https://spdx.org/licenses
- C/C++/objc/objc++
- Python
- Shell Scripts
- CMake, GNUmakefile
While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
use different header conventions.
doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

The thread affinity setting in OIDN can break multithreading on some CPUs.
While this leads to somewhat worse performance on CPUs that do work correctly,
it's better than having some CPUs use only half the cores.
This is a code refactor in preparation of supporting canvas
compositing. See {D12466}.

It's equivalent to the OpenImageDenoise prefiltering option in Cycles.
See D12043.
Prefilter modes:
- None: No prefiltering, use when guiding passes are noise-free.
- Fast: Denoise image and guiding passes together. Improves quality when
guiding passes are noisy using least amount of extra processing time.
- Accurate: Prefilter noisy guiding passes before denoising image.
Improves quality when guiding passes are noisy using extra
processing time.

Related to {T77023}. When using many Denoise nodes the memory in OIDN
are allocated up front. A mutex could stall the process until. This
change will allocate the memory after it received the lock.
