Fix race condition when multiple file/asset-lists are running at once

E.g. opening a file with an asset viewer and an Asset Browser could cause one
of them to not load its files properly. That is because there was only one
`wmJob` per scene so when the first one was done it would end the other one(s).
I think this would be a problem in master for the regular File Browser too.

Instead of setting the scene as owner of the job, use the file-list, so that
each file/asset-list gets its own job.

Cycles: add back random walk subsurface scattering

* shade_surface now samples either a BSDF or BSSRDF to continue the path, and
depending on that will continue with intersect_closest or intersect_subsurface.
* Then intersect_subsurface kernels does ray-tracing and scattering below the
surface. If an exit point is found, it returns to shade_surface.
* Since shade_surface is called twice, direct lighting is evaluated both for
the BSSRDF and any (typically specular) BSDF, since only doing either is
quite noisy.
* Note most files use Christensen-Burley so will render differently.
* subsurface_random_walk should be split up into smaller functions, but I've
kept it like the current implementation now, will split it up in a later commit.

Cleanup: add utility functions write writing ray and isect to integrator state

Fix CUDA runtime compilation after last commit

Merge branch 'master' into temp-spreadsheet-instances

Geometry Nodes: Make cone primitive 2m tall by default

This gives the cone mesh primitive more pleasing proportions by default.

Geometry Nodes: Move cone primtive to rest on its base by default

This is generally what people expect when generating a cone. Note that
this translation currently happens after the rotation, but since the rotation
will likely be removed in the future, that won't be a problem for long.

EEVEE: Add Shadow option as GPencil Layer level

Now there are tow options to enable the shadows, at material level and layer level.

Also, renamed `show_shadows` to `use_cast_shadows`

Geometry Nodes: Implicit interpolations to and from the edge domain

This patch adds the remaining 6 interpolations for mesh domains.
The new interpolations are:
- Corner / point / polygon to edge
- Edge to corner / point / polygon

After this it is possible to adapt an attribute to and from every
mesh domain. This is simple to test with the "Attribute Convert" node.

Though, as a note for the future, there are still some improvements
possible to the interpolations, like lazily calculating values for the
interpolations where it's possible, and slightly improving the
algorithms used for some interpolations, like using corner angles
for polygon to point.

Fix Cycles NaN assert in random walk SSS due to very small throughput

Now terminate if there are many bounces and the throughput gets so small
that we get precision issues.

Cycles: Move GPU display texture state tracking to base class

While is still not ideal and feels rather fragile, at least now the
actual implementation of a sub-class is straightforward and does not
require state tracking.

Cycles: refactor CPU/megakernel for more flexible execution order

Previously it would call kernels in a fixed order, which becomes harder with
a more complex state machine for SSS and volumes. Further, there was code
duplication in that kernels would be indicate the next kernel to execute, and
check if the current kernel needs to be executed.

Instead use queued_kernel on both CPU and GPU, and implement the megakernel as
a switch statement using this value.

LibOverride: fix code trying to auto-resync linked overrides.

This is not only potentially extremely expensive, it is also fairly
futile, and code is not designed to handle it currently anyway (could
easily end up in inifinite loops and other crashes).

LineArt: Added back the missing "allow_clipping_boundaries" option.
