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 Lighten mix mode in the Mix RGB node is wrong for factors less than
one. The lighten blend mode is a simple component-wise maximum in EEVEE,
Cycles, and other implementations. While the compositor seems to define
it as a weighted maximum using the factor as the weight. It should be
noted that its Darken counterpart is correctly implemented for the same
node, so Lighten should follow, which this patch do.
GPU compositor shares the EEVEE code, so it is already correct.

Include counts of some headers while making full blender build:
- BLI_color.hh 1771 -> 1718
- BLI_math_color.h 1828 -> 1783
- BLI_math_vector.hh 496 -> 405
- BLI_index_mask.hh 1341 -> 1267
- BLI_task.hh 958 -> 903
- BLI_generic_virtual_array.hh 509 -> 435
- IMB_colormanagement.h 437 -> 130
- GPU_texture.h 806 -> 780
- FN_multi_function.hh 331 -> 257
Note: DNA_node_tree_interface_types.h needs color include only
for the currently unused (but soon to be used) socket_color function.
Future step is to figure out how to include
DNA_node_tree_interface_types.h less.

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:

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.
See P2788 for the script that automated these edits.

The crash was caused by allocating an uninitialized amount of memory.
This fix initializes a bunch of variables that could cause the error.
It should be possible to also fix this in the function that actually uses
the uninitialized memory, but that could cause unknown consequences
that are a bit too risky for 3.0. Just initializing some variables should
be safe though. For more details see D13369.

This is a code refactor in preparation of supporting canvas
compositing. See {D12466}.
No functional changes, all canvases are at (0,0) position matching

The mixing function was designed to give correct results for Mix values of
-1, 0, and +1, but the behavior between these points was not linear. This is
unavoidable, because the function depends on both Mix and Mix^2 (by
multiplying value and mf) so they could not cancel out completely.
The new formula simply calculates the weighted sum without trying to invent
a smooth function.
Value for MixGlareOperation is now passed directly without scaling because
it is then easier to use.
Note that the previous formula performed max() twice for both input image
and the result, now there is just one max() per channel because the glare
input can't be negative.

This removes a lot of unnecessary code that is generated by
the compiler automatically.
In very few cases, a defaulted destructor in a .cc file is
still necessary, because of forward declarations in the header.
I removed some defaulted virtual destructors, because they are not
necessary, when the parent class has a virtual destructor already.
Defaulted constructors are only necessary when there is another
constructor, but the class should still be default constructible.
