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 is contains the initial capture pipeline for planar probes.
It requires work to generate the correct view to capture and to include
the result during ray tracing. These will be developed in a separate PR.
This PR detects if a planar probe is active in the scene. If this is
the case the planar probe pipeline will be activated. During rendering
this is done by querying the depsgraph, during viewport drawing this
is done during sync. If an planar probe is detected and the pipeline
wasn't activated. The pipeline will be activated and the sampling
will be reset to ensure the pipeline is filled with all objects.
Per object the user can set the visibility of the object in planar
reflections.

For a reflection plane the resolution and clipping offset can be set.
EDIT: Resolution option was removed because too complex to
implement with the little time we have at the moment.

This PR implements an initial drawing tool that can already be used for testing.
While this is not fully feature complete (compared to the current grease pencil draw tool) the following is already implemented:
* Pressure support for radius and opacity.
* Material color and vertex color support.
* New active smoothing algorithm based on curve fitting.
* Simplify algorithm as a post-process step.
Some deliberate limitations include:
* The drawing plane is always the front plane. Drawing on surfaces is also not supported.
*
The current approach has not been optimized for performance yet. The goal was to have a straightforward implementation
first and then focus on performance later.
There are numerous parameters in the code that are hard-coded for now. These should be exposed at some point, potentially as user settings.

Dummy mistake in commit(s) a few months ago that fixed/improved handling
of parenting between objects in liboverride context, trying to access an
Enum propoerty as an int one...
This will have to be backported to 3.6LTS as well.
The `blender-v4.0-release` branch would not build because some parts of grease pencil v3 were still exposed when experimental features are disabled.
This is hiding the relevant parts behind `#ifdef WITH_GREASE_PENCIL_V3` to make sure they are only built when the experimental features is enabled.

Since 3b5df8a7ea, we are displaying a "canvas picker" in the 3DView
header. In weightpaint mode, this gives us the active vertexgroup to
paint on, however the header wasnt updating when changing the
vertexgroup elsewhere (e.g. from the Properties Editor).
Part of #112186.

There are a couple of functions that create rna pointers. For example
`RNA_main_pointer_create` and `RNA_pointer_create`. Currently, those
take an output parameter `r_ptr` as last argument. This patch changes
it so that the functions actually return a` PointerRNA` instead of using
the output parameters.
This has a few benefits:
* Output parameters should only be used when there is an actual benefit.
Otherwise, one should default to returning the value.
* It's simpler to use the API in the large majority of cases (note that this
patch reduces the number of lines of code).
* It allows the `PointerRNA` to be const on the call-site, if that is desired.
No performance regression has been measured in production files.
If one of these functions happened to be called in a hot loop where
there is a regression, the solution should be to use an inline function
there which allows the compiler to optimize it even better.

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.
Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
Pull Request #110944
Use const arguments for array input arguments as there
is no reason for them to be modified.
Using non-const arguments meant some functions
(uiTemplateNodeSocket for e.g.) couldn't use 'const' qualifier so the
generated type signature would match.
Also use suffix "_num" instead of "_len" for array lengths, ordering
these arguments after the array (in keeping with Blender's conventions).
Similar to ded695bc73.
Note that the third 'storage' codepath is not affected currently, this
is almost dead code actually, might rather consider removal of it
altogether.
No behavioral nor performance changes are expected with this commit.
Implements the rest of #101689, after 5e9ea9243b.
- `vdata` -> `vert_data`
- `edata` -> `edge_data`
- `pdata` -> `face_data`
- `ldata` -> `loop_data`
A deeper rename of `loop` to `corner` will be proposed as a next
step, and renaming `totvert` and `totedge` can be done separately.

Implements part of #101689.
The "poly" name was chosen to distinguish the `MLoop` + `MPoly`
combination from the `MFace` struct it replaced. Those two structures
persisted together for a long time, but nowadays `MPoly` is gone, and
`MFace` is only used in some legacy code like the particle system.
To avoid unnecessarily using a different term, increase consistency
with the UI and with BMesh, and generally make code a bit easier to
read, this commit replaces the `poly` term with `poly`. Most variables
that use the term are renamed too. `Mesh.totface` and `Mesh.fdata` now
have a `_legacy` suffix to reduce confusion. In a next step, `pdata`
can be renamed to `face_data` as well.

While setting the parent object itself already had its dedicated
liboverride apply function to avoid resetting other related properties
like the invert parent matrix, other related properties also had custom
setter callbacks with similar effect.
This commit fixes the propblem for the `parent_bone` and `parent_type`
properties by adding a custom liboverride apply callback for them too.
The "No Cache" simulation nodes option effectively changes the cache
to work in a "realtime mode" where there are only two states, the
current and previous frame. Whenever the current frame doesn't
increase, the previous state should reset. This didn't happen
properly, and it was hard to verify because the code was shared
with the regular "cache on" mode.
Instead, separate the caching more in the code, using a different
struct to store the two "realtime" states. Also clarify that we
don't support animation of the "No Cache" option by disabling
support for that in RNA.

- "Front"/"Back": 'put something at the front/back' or 'the front/back
face of something'. (e. g. the Empty Image options, Depth and Side
option, both use the same strings as enum, which should be avoided
in some languages).
- "Flip": invert, as in normals, or mirror, as in an image.
- "Path": a path to a resource, in general a file but sometimes a
datablock, as opposed to a trajectory in space.
- "Join": disambiguate for the Grease Pencil operator, which may use a
different word as that for meshes.
- "Wave": an ondulating motion, as opposed to a fluid dynamics motion.
- "Step": can mean the distance between two things, or a number of
times to do something. In this case it is better to use the plural.
- "Edge": generally the edges of a mesh, but can also mean edge
detection. Additionally, it was used for the option to enable
Freestyle. This was changed to "Use Freestyle".
- "Boundary": the limit of a grease pencil drawing for filling
purposes, as opposed to the external limit of a (non-manifold) mesh.
- "Rotations": can be translated to something like "Turns", in the
context of a spiral.
