Test cases that uses compute shaders were exited when run on platforms
not supporting compute shaders. Since 4.0 Blender requires a platform
that supports compute shaders.
We should eventually phase out `GPU_compute_shader_support` as it
would always return true. Note that in OpenGL a platform is mentioned
that doesn't support compute shaders, but that is from an old driver
and should be save to remove as well.

- Expected results should come before actual result.
- Add test case for 8192 bytes as apple has a push constants size of 4096.
- Add more variation to the first order test data.
Improvements detected when working on vulkan backend and validated they
work on metal and opengl as well.

Blender 4.0 requires OpenGL 4.3 which always support SSBO's.
Platforms that don't support enough SSBO bind points will be marked
as unsupported.
Users who start Blender on those platforms will be informed via a
dialog. This PR also updates the `--debug-gpu-force-workarounds`
to match our minimum requirements. Note that some bugs are still
there that should be solved in other PRs:
* Workbench only renders the object using a unit matrix this is because
there is a bug in the workaround for shader_draw_parameters
* Navigating with middle mouse button is not working. Unsure what the
cause is, but might be a missing feature check in the OpenGL backend.

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/
In Vulkan multiple commands can be in flight simultaneously.
These commands can share resources like descriptor sets or push
constants. When between commands these resources are updated
a new version of the resources should be created.
When a resource is updated it should check the submission id of the
command buffer. If this is different than last known by the resources,
the previous resources should be freed.
If the submission id is the same than previously it has to create a
new version of the resource to not intervene with other commands that
uses the resource before the update.
When the resource wasn't updated between multiple usages in the same
submission id it could reuse the previous resource.
This PR introduces a `ResourceTracker` and a `SubmissionTracker`.
A submission tracker can check if the command buffer is submitted.
In this case all resources of the resource tracker should be freed.
Unmodified resources in the same submission can be shared.
A resource tracker will keep track of all resources that are in
flight. After the resources are used (submission + execution) have
finished the resources can be cleared.

The _gpu_ prefix is redundant as they are inside a namespace
and run as part of a test suite that already contain the name
gpu. (GPUOpenGLTest)
This patch also moved the texture test cases to its own
compile module.
