Optimization of EEVEE Next's Virtual Shadow Maps for TBDRs.
The core of these optimizations lie in eliminating use of
atomic shadow atlas writes and instead utilise tile memory to
perform depth accumulation as a secondary pass once all
geometry updates for a given shadow view have been updated.
This also allows use of fast on-tile depth testing/sorting, reducing
overdraw and redundant fragment operations, while also allowing
for tile indirection calculations to be offloaded into the vertex
shader to increase fragment storage efficiency and throughput.

For some reasons, `WM_jobs_stop` and `WM_jobs_kill` would use their own
'type' of function pointer - and not even a matching one!
Among (many) other reasons why this was bad, it required very stupid
casting from code using these functions - and made editing wmJob `startjob`
signature needlessly complicated.
Enable tests for EEVEE Next.
As a workaround for allowing the use of EEVEE Next (still an
experimental feature) with `--factory-startup`, `arg_handle_engine_set`
enables the feature when `-E BLENDER_EEVEE_NEXT` is used.
In addition, EEVEE Next is always registered, so it's available when
calling `WM_init`.
If it's actually disabled, it will be immediately unregistered after that.
Notes:
- `get_gpu_device_type` always fails with error:
> GPU API is not available in background mode
- Setup and tests are the same as EEVEE. There are many tests that
only make sense for Cycles, and many EEVEE Next features that are
not actually tested.

When the scene has reflection probes the sampling would be reset
each frame making the viewport always redraw and not resolve.
The reason was a logic error that was introduced when we introduced
a less flickering update for reflection probes.

The probe capture pipeline still had some bindings from the previous
implementation. This could result in overwriting the `gbuf_header_tx`
with the incorrect texture as it was sharing the same binding.
This PR removes the unused light probe bindings.

When the scene has exact 128 resources or a multiple in the scene
Blender crashes as the velocity buffer doesn't allocates the
right amount of space inside its buffer.

This patch implements the Keying Screen node for the Realtime
Compositor. Draw data was introduced to the Movie Clip ID to allow
caching of the keying screen.

This add a way to use a software clip plane in the
prepass shader (surf_depth_frag.glsl).
The benefit of using this instead of gl_ClipDistance
is that the rasterization pattern is given to match.
Which means that only the prepass shader have to use
this.
This is slow and should only be enabled when needed.
Overlay engine is currently responsible to initialize the framebuffers
depth_in_front texture. This is a hack and hasn't been ported to
Overlay-Next (yet). This PR skips copying the depth_in_front texture
when it isn't initialized yet.
Issue detected when working on Vulkan backend due its more
strictness.

The ideal would be to increase the version file, but this would make
the versioning code a bit messy, and it was a recent error
(it shouldn't affect many users).
`DRW_drawdata_get` reuses the same `DrawData` for all duplis,
so they all end up using the same `ObjectHandle` and `ObjectKey`,
which breaks motion vectors.
* Don't use `DRW_drawdata_get`.
* Simplify `ObjectKey`.
This also solves the issue of objects created "on the fly" always having
the `ID_RECALC_ALL` flag.

Since garbage collection of texture pools happens every time
`drw_manager_init` is called, interleaved calls to different
`DRW_draw`/`DRW_render` functions can result in a constant cycle of
creating/releasing textures.
This PR changes texture pools to only release textures that have not
been used for N garbage collection cycles.
I chose 8 as default since I think is high enough to avoid the issue
while it's unlikely to cause any major spike in memory consumption.

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.

The case when there were no material indices, multiple materials, and
the mesh used hiding wasn't handled after 55970fa367.
This is a simple parallel loop adding up the non-hidden triangles.
Hair and Curves need to call `DRW_curves_update` before
`geometry_steps_fill`, otherwise the copied geometry is just
uninitialized data.
However, doing so triggers an assertion:
> DRW_render_instance_buffer_finish had not been called before drawing.
This PR ports the `DRW_hair/curves_pos_buffer_get` functions to the new
`draw::Manager` API, so it can be called at any arbitrary point.
It also changes `VelocityModule::geometry_map` to use `uint64` keys
instead of `ID` pointers, since the same particle system can be used on
different objects and have multiple geometries.
Notes:
* The new functions are only used for
`VelocityModule::step_object_sync` on image renders. Using them
elsewhere would require modifying the old draw manager to do the
init/update/free setup.
* Only the compute shader version has been ported.

Implement a clip distance to irradiance grids, so surfaces farther than
the threshold don't generate surfels.
Align the capture view matrix to the probe rotation.

This makes the SSS processing more isolated to avoid
side effects in other passes.
Also this allow more optimization using LDS.
The radiance buffer is created by a setup phase using
direct and indirect lighting.
Splitting this into its own compute pass also fixes
a pass merging issue on Metal.

This avoid confusion outside of the shader node GLSL code.
The issue also is that Metal allow float to cast to bool
implicitly but this create a compilation error on
OpenGL.
Scenes that only uses a world probe would didn't work. Raytracing
would look for the closest light probe, didn't find any and shader
would use undefined behavior to sample in the reflectionProbes texture.
In some cases this resulted in correct results when the world was
located on layer 0 with subdivision 0. In any other case this would
sample incorrect incoming light what lead to black reflections.
This PR fixes this by returning the world probe when no nearest light
probe cound be found.

This adds a new entry to the split sum LUT to isolate
the effect of the F82 tint.
The application of the tint part is similar to cycles
and uses the same way for precomputing the `b` factor.
Results matches almost perfectly to the extent of the
split sum approximation.
Note that this removes the unused LTC MAG LUT for
EEVEE next to make space for the new table. It can still
be added back if needed.

Texture Atomics have been added in Metal 3.1
and enable the original implementations of
shadow update and irradiance cache baking.
However, a fallback solution will be
required for versions under macOS 14.0 utilising
buffer-backed textures instead.
This patch also includes a stub implementation if
building/running on older macOS versions which
provides locally-synchronized texture access in
place of atomics. This enables some effects to be
partially tested, and ensures non-guarded use
of imageAtomic functions does not result
in compilation failure.

This keeps the behavior similar to the Disney BRDF, where 0.5
is neutral and lower/higher values respectively decrease/increase
the dielectric specular. But it's more correct in that it's not
an arbitrary scale on Fresnel, but rather adjusting the IOR.
