Fixed more cases where attributes weren't being reinitialized
on switching PBVH mode:
* When PBVH_GRIDS and PBVH_BMESH force attributes into simple
array mode they no longer override simple_array in the
SculptAttributeParams parameters, instead they set a field
in SculptAttribute itself. Thus if the attribute is
reinitialized in another mode it won't retain the simple_array
parameter.
* sculpt_attribute_ensure_ex now calls sculpt_attr_update if
the attribute already exists.
* Fixed a bug from a couple commits ago that set
SculptAttribute.data_for_bmesh wrong.
PBVH draw code now builds coarse triangle index buffers
for multires. Note that the coarse grids can be at any
multires depth but is currently hardcoded to 1.
Previously the sculpt box trim operator always created face sets,
but after face sets became optional it only modified them if they
already existed. Absent a better way to turn the behavior on and off,
the fix is to just always create face sets.
Before f1c0249f34 the material was assigned to the previous
slot rather than the next. Though the behavior is arbitrary, there
is no reason to change it.
The `transform_convert_clip_mirror_modifier_apply` code is made more readable by:
- decreasing indentation;
- removing `axis` and `tolerance` variables;
- renaming `int clip` to `bool is_clipping`;
The comment of `solve_cubic()` put the coefficients of the to-be-solved
cubic equation in the wrong order. This is now fixed.
No functional change, just a comment fix.
When the line was very thin the precision of the thickness
calculation was not precise enough.
The algorithm has been improved. This affects SVG and PDF.
* Make it clearer that contrib isn't shipped with releases, by already excluding it in beta.
* Improve the UI by hiding the "Testing" enum item in these case.

In preparation to sanatize the mask texture and color texture in sculpt code. In sculpt
mode the mask texture is read from mtex, leaving the mask_mtex when we want to use color
textures in sculpt mode.
Having all packages on one line made reviewing changes difficult.
Also note why Python modules are needed (with some TODO's where I wasn't
able to find any reason given for their inclusion).
The PKGCONFIG file exposes the OPUS include: requiring <opus/opus.h>
to be replaced with <opus.h>. Manipulate the PKGCONFIG file instead of
patching the source since the small change is only needed in one place.
Meson is built as part of external_python_site_packages,
without this dependency it would be called before being built.
Also remove Meson as a build requirement since the version is used.
Adds an early return if Position/Offset inputs won't lead
to any changes in the Geometry.
It now also compares with the read-only Position attribute instead of
getting it for write only, to work correctly with Copy-on-Write.
Before, the `is_same`-check only worked for geometry created
in the node tree.

There has been an attempt to reorganize this part, however, it seems that didn't compile on HIP, and is reverted in
rBc2dc65dfa4ae60fa5d2c3b0cfe86f99dcb5bf16f. This is another attempt of refactoring. as I have no idea why some things don't work on HIP, it's
best to check whether this compiles on other platforms.
The main changes are creating a new struct named `MeshLight` that is shared between `KernelLightDistribution` and `KernelLightTreeEmitter`,
and a bit of renaming, so that light sampling with or without light tree could call the same function.
Also, I noticed a patch D16714 referring to HIP compilation error. Not sure if it's related, but browsing
https://builder.blender.org/admin/#/builders/30/builds/7826/steps/7/logs/stdio, it didn't work on gfx1102, not gfx9*.

The OpenVDB delay loading of voxel leaf data using mmap works poorly on network
drives. It has a mechanism to make a temporary local file copy to avoid this,
but we disabled that as it leads to other problems.
Now disable delay loading entirely. It's not clear that this has much benefit
in Blender. For rendering we need to load the entire grid to convert to NanoVDB,
and for geometry nodes there also are no cases where we only need part of grids.
To avoid issues with lights being either skipped or sampled unnecessarily
when the exposure is set low or high.

* preempt_attr was copied from CUDA, but not used in HIP.
* Remove shadowed variable before conditional in EnvironmentTextureNode code.

Expand the motion path frame range options with an extra option "Manual
Range". When chosen, Blender will not automatically update the path
range any more.
Additionally, the start/end frame fields are greyed out in the UI when
one of the automatic range options is selected (i.e. all but the new
"Manual Range" one). It is still possible to set the start/end frame
temporarily, but the original behaviour (of recomputing those on update)
remains.
