This patch enables bound box check when loading geometry
into line art. Works with overscan as well. Will discard
object if its bbox completely lies in one side of the
clipping space frustum.

For scenes that have a lot of edges, this could potentially

After looking into task isolation issues with Sergey, we couldn't find the
reason behind the deadlocks that we are getting in T87938 and a Sprite Fright
file involving motion blur renders.
There is no apparent place where we adding or waiting on tasks in a task group
from different isolation regions, which is what is known to cause problems. Yet
it still hangs. Either we do not understand some limitation of TBB isolation,
or there is a bug in TBB, but we could not figure it out.
Instead the idea is to use isolation only where we know we need it: when
holding a mutex lock and then doing some multithreaded operation within that
locked region. Three places where we do this now:
* Generated images
* Cached BVH tree building
* OpenVDB lazy grid loading
Compared to the more automatic approach previously used, there is the downside
that it is easy to miss places where we need isolation. Yet doing it more
automatically is also causing unexpected issue and bugs that we found no
solution for, so this seems better.
Patch implemented by Sergey and me.

Under some circumstances using task isolation can cause deadlocks.
Previously, our task pool implementation would run all tasks in an
isolated region. Now using task isolation is optional and can be
turned on/off for individual task pools.
Task pools that spawn new tasks recursively should never enable
task isolation. There is a new check that finds these cases at runtime.
Right now this check is disabled, so that this commit is a pure refactor.
It will be enabled in an upcoming commit.
This fixes T88598.

This patch adds the Randomize options that exist in the Array modifier to the offset modifier.
Currently the patch uses
```
BLI_findindex(&gpf->strokes, gps);
```
to get the index of the current stroke for making each stroke a different seed value. This is how the noise modifier also gets the stroke seed value and it is noted there as well that this method is slow, and should be fixed in the future with another method of getting the stroke index.
Other methods were explored such as using the total number of points of the stroke, but that makes the randomize options incompatible with other modifiers before it such as Multiple Strokes, Array, Build, and Simplify.

When having a checkbox and a value both in one row together with an
animation decorator it is questionable whether the decorator should act
on animating the checkbox or the corresponding value. At the moment,
usage in modifiers does not seem to be very consistent:
Here the animation decorator works for animating the checkbox:
- `Build` (greasepencil) > `Factor` (this was reported and is changed in
this patch to act on the value instead of the checkbox)
- `DataTransfer` > `Topology Mapping` > `Max Distance` (this I guess
should also act on the value instead of the checkbox)
- `Edge Split` > `Edge Angle` (questionable)
- `Mirror` > `Merge` (questionable)
- `Screw` > `Merge` (questionable)
- `Wireframe` > `Crease Edges` (questionable)
Here the animation decorator works for animating the value:
- `VertexWeightEdit` > `Group Add/Remove Threshold`
- `Decimate` > `Symmetry`
So in this patch only the behavior in the greasepencil Build modifier UI
is changed, since I think it is quite obvious that one would more often
use the decorator for animating the factor value than for animating the
checkbox.

Materials used in grease pencil modifiers have the requirement that they
are already used on the object. In the UI dropdown, this restriction is
ensured by calling uiItemPointerR with appropriate searchptr and
searchpropname, so only giving the user the choice of materials already
used on the object.
From python though, it was still possible to assign materials outside of
this this restriction. This led to reports like T86981 [which have been
partially solved by clamping the material index in the modifier code to
be in the valid range].
Now make sure we dont assign "invalid" materials through RNA by
appropriate RNA pointer functions.
This also adds a proper warning (red, alert) in case of the LineArt
modifier if such a invalid material is still in the file [same as other
modifiers already do].

After some back and forth with the GP module and some artists, this
option was deemed not that useful. The use case was considered too
obscure so we'll remove it.
It is still posible to have this functionality by using the vertex
weight modiifers or manually clamping the weights.
