Update to the new naming convention for `Light Probes`:
`Reflection Cubemap` -> `Sphere`
`Reflection Plane` -> `Plane`
`Irradiance Grid` -> `Volume`
Note that this breaks the Python API (`bpy.types.LightProbe.type`).

This PR reuses the scene specific reflection probe resolution for all
reflection light probes in the scene. The target is to have a automatic
detection for the resolution. But as long as we don't have a mechanism
for detection it is better to not introduce a new UI element that will
be removed within the foreseen future.
This setting is currently used by EEVEE and EEVEE-Next. EEVEE supports
resolutions upto 4096px. This will be clamped to 2048 when using
EEVEE-Next.
The motivation for this is that EEVEE-Next will soon replace
EEVEE and 4096 can then be removed from the choices that the user can
made. Adding as separate option could need synchronization, and that
option would also be temporary as it will be removed by the resolution
detection mechanism.

Shadow Map Ray Tracing is a technique that ray cast against the shadow
depth buffer. The technique is described in "Soft Shadows by
Ray Tracing Multilayer Transparent Shadow Maps".
Note that we only implement the single layer approach since storing
multiple depth is prohibitively expensive.

Add the features missing from #107176
* Irradiance integration.
* Self-shadows.
* Receive shadows from shadow maps.
Shadow tagging works by iterating all the froxels in a
compute shader and tagging the exact same position
that will be sampled by the volume scatter shader.
Froxels that are fully transmissive, have no scattering,
or are behind opaque geometry, are skipped.
It also adds a LoD bias parameter for shadow tagging,
driven by the volumetric tile size.
This works for punctual shadows, but directional lights
would need a way to support re-direction between levels
at sampling time, which is out of the scope of this PR.

On a user level this view transform provides much better handling of colors in
the over-exposed areas.
With this configuration the following display devices are available, including
AgX view transform for them:
* sRGB
* Display P3
* Rec.1886
* Rec.2020
NOTE: There is no Filmic view transform available for the newly added display
devices.
AgX also brings an implementation of False Colors view transform, which replaces
Filmic-based, and is available for all display devices.
The backward compatibility is preserved. The new files will default to AgX view
transform, which makes it non-forward compatible.
More technical details is available in the original PR #106355.
Please note that the PR has been split into more incremental changes when
was landing.

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.
Add a High Dynamic Range option in the Color Management > Display panel.
This enables display of extended color ranges above 1.0 for the 3D
viewport, image editor and render previews.
This requires a monitor that can display HDR colors, and a view
transform designed for HDR output. The Standard view transform works,
but Filmic does not as it was designed to bring values into the 0..1
range for SDR displays.
This patch is limited to allowing the display to visualize extended
colors, but does not include future looking work to better integrate HDR
into the full workflow.
It is implemented by rendering to high bit-depth texture formats for
the user interface, and uncapping the color range in color management.

This is currently meant mainly for testing, when "Developer Extras" is
enabled. The goal is to make interactive Hydra export and USD file export
identical. We are not there yet, and having the ability to compare both
in the viewport and automated tests should help us get and stay there.
Ref #110765
This is a full rewrite of the raytracing denoise pipeline. It uses the
same principle as before but now uses compute shaders for every stages
and a tile base approach. More aggressive filtering is needed since we
are moving towards having no prefiltered screen radiance buffer. Thus
we introduce a temporal denoise and a bilateral denoise stage to the
denoising. These are optionnal and can be disabled.
Note that this patch does not include any tracing part and only samples
the reflection probes. It is focused on denoising only. Tracing will
come in another PR.
The motivation for this is that having hardware raytracing support
means we can't prefilter the radiance in screen space so we have to
have better denoising. Also this means we can have better surface
appearance with support for other BxDF model than GGX. Also GGX support
is improved.
Technically, the new denoising fixes some implementation mistake the
old pipeline did. It separates all 3 stages (spatial, temporal,
bilateral) and use random sampling for all stages hoping to create
a noisy enough (but still stable) output so that the TAA soaks the
remaining noise. However that's not always the case. Depending on the
nature of the scene, the input can be very high frequency and might
create lots of flickering. That why another solution needs to be found
for the higher roughness material as denoising them becomes expensive
and low quality.

Port Ambient Occlusion to EEVEE Next.
Add support for the AO Node and the AO RenderPass.
AO shading integration is still missing.
This also fixes the Shadow RenderPass.

This commit implements described in the #104573.
The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).
This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.
This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale
This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.
Running `make update` will initialize the local checkout to the changed
repository configuration.
Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).
