Changing 3D curve properties while viewport rendering was active
resulted in an error, because Cycles would attempt to update the
acceleration structure containing the curves, but that acceleration
structure was built without the
`OPTIX_BUILD_FLAG_ALLOW_UPDATE` flag allowing updates. This
fixes that by adding the flag to all curve build inputs.
Ideally could just use the same flags as for other build inputs and
differentiate between viewport and final rendering (based on
`bvh_type`), but that's not currently an option since the same flags
have to be specified to query the curve intersection module in
`load_kernels()`, where that differentiation is not known. See also
commit 5c6053ccb1.

The primitive tool didn't write to the `fill_opacity` attribute meaning that primitives wouldn't
show up correctly when using fill materials with a strength < 1.
The fix does multiple things:
* Make sure to create and write to the `fill_opacity` attribute if necessary.
* Remove the `skipped_attribute_ids` function and build the set of attributes to skip
where the attributes are written to. This is more flexible.

Snapping the 3D cursor to a grease pencil selection would include
locked layers in the computation of the centroid. This is inconsistent
with 4.2.
The fix makes sure that we skip over layers that are locked.

This commit removes support for Vega GPUs from the AMD HIP backend of
Cycles. This is being done as:
- AMD no longer provides official support for Vega GPUs in their
ROCm software.
- Vega GPUs have rendering artifacts on all supported platforms,
and as a result of the reduction of support from AMD, are unlikely
to be fixed. Rendering artifacts include.
- The incorrect shading of volumes (Windows and Linux)
- Missing intersections on many meshes with HIPRT
- Crashing rendering subsurface scattering materials (Linux)
- And more.

Previously, we initialized the layers and groups to hide masks.
For layers this makes sense, because they don't have any masks
by default, but for groups it makes more sense to show masks
by default for all the layers inside.

The default value for `FLOAT_COLOR` attributes is white. We can't
change this default easily.
This fix will initialize the attributes accessed through the high-level
python API with their expected default value. In the case of
vertex colors, this is fully transparent black.

In lieu of fixing the root cause, this commit requires the object to be
in object mode to duplicate particle systems, which works around the
issue because the problem is with particle edit data. This is a pragmatic
choice to focus development efforts on replacing the particle system.
Example:
Step is 3
Action starts at 1, so the action will try to export frames 1 / 4 / 7 / 10, etc...
But full object backing is enable, and scene starts at 0.
So cached data are on frame 0 / 3 / 6 / 9 / 12, etc...
When we are trying to export the action on armature after the full bake on empty, we are trying to retrieve frame 1, but cache was on 0 / 3 / 6 / 9
error log will go to stderr, and others to stdout
A new parameter in operator to set the loglevel from command line bpy.ops.export_scene.gltf(loglevel=logging.INFO)
If not set from the ops, value is -1, and is set, as before, from the bpy.app.debug_value
Introduced with 5fff95f519.
There were several issues:
* The indices into `edit_points_vflag` are incorrect. They need to be offset
by the start offset of the drawing.
* The code was writing to `edit_points_vflag` even if the layer is locked.
But the size of the `edit_points_vflag` buffer is not counting locked layers.

The `osl_wavelength_color_vf` intrinsic was missing an implementation for
OptiX, causing a link error when attempting to load OSL shaders using the
wavelength node.

This reverts commit 0a70360eb6. That's
because it caused issue #129366 which is much more serious, and the
cause is not obvious so far. Another fix will be submitted for the
original issue.
