a8feb20e1c DNA: Move irradiance grid light cache data to Object level
This is the first step for refactoring the lightcache system.
Each probe instance (as in `Object`) will now store its own baked data.
The data is currently stored in uncompressed readable format.

This introduces two new operators for baking to avoid confusion with
the previous light baking pipeline. These do nothing other than
creating empty caches that will be populated by EEVEE later on.

The DNA storage is made to be able to include multiple caches
in case of baked simulation over time but it isn't yet supported.

I prefer to keep the implementation simple for now as the long term
goals for this feature are uncertain.
There is still a type flag (`LightProbeObjectCache.cache_type`) that
will be used for versioning.

The naming convention of structs is a bit weird but that's all I
found in order to avoid interfering with the old scene light cache
that is still used by (old) EEVEE.

Related task #106449.

a12a8a71bb Remove "All Rights Reserved" from Blender Foundation copyright code
The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.

The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.

However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.

This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:

    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This program is free software ...

This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.

2e77a8f974 Render: Add operators to add all used or remove all unused lightgroups
These operators build a list of all lightgroups that are used by the view layer's
scene and either add all used lightgroups that are not part of the view layer yet
or remove all lightgroups in the view layer that are not being used.

ad35453cd1 Cycles: Add support for light groups
Light groups are a type of pass that only contains lighting from a subset of light sources.
They are created in the View layer, and light sources (lamps, objects with emissive materials
and/or the environment) can be assigned to a group.

Currently, each light group ends up generating its own version of the Combined pass.
In the future, additional types of passes (e.g. shadowcatcher) might be getting their own
per-lightgroup versions.

The lightgroup creation and assignment is not Cycles-specific, so Eevee or external render
engines could make use of it in the future.

Note that Lightgroups are identified by their name - therefore, the name of the Lightgroup
in the View Layer and the name that's set in an object's settings must match for it to be
included.
Currently, changing a Lightgroup's name does not update objects - this is planned for the
future, along with other features such as denoising for light groups and viewing them in
preview renders.

c434782e3a File headers: SPDX License migration
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.
