Fix T88934: Crash with line node count input < 0

Some of the primitive nodes can return null in an error condition.
This is confusing mixed with adding a maderial slot in calling
functions. This is the second crash caused by that confusion. It's
simpler to add the slot right when allocating the mesh, and it will
lend itself better to copy & paste coding in the future.

Differential Revision: https://developer.blender.org/D11530

Revert "Cleanup: use cpp new/delete."

This reverts commit 43464c94f4def8689dd99a9e459f5ff77420d27b.

Cleanup: add newline at end of bl_ui/__init__.py

Add newline at end of `bl_ui/__init__.py`

No functional changes.

Move `Workspace` and `WindowManager` properties to poselib add-on

Move `WorkSpace.active_pose_asset_index` and `WindowManager.pose_assets`
from Blender to the Pose Library add-on. Since that add-on is the only
code using them, they belong there.

Cleanup: replace NULL with nullptr.

Cleanup: use cpp new/delete.

Asset Browser: explain reason "Open Blend File" is disabled

Use `Operator.poll_message_set()` to explain to users why the "Open
Blend File" operator is disabled in the Asset Browser.

Merge branch 'master' into xr-controller-support

Update pipeline config

Cleanup: Separate fdots extraction in own compile unit.

Cleanup: Separate compile unit lines_paint_mask.

Cleanup: Separate compile unit lines_adjacency.

Cleanup: Separate compile unit edituv.

Cleanup: replace typedef structs with structs.

Fix T88719: Attribute Remove node input field does nothing

An unlinked multi-input socket was not handled correctly.

Merge remote-tracking branch 'origin/master' into temp-lineart-contained

Merge branch 'master' into override-recursive-resync

CMake: Fix `FindClang` not finding system clang on linux in some cases.

In Debian e.g. Clang is part of LLVM, so we need to also check its root
directory sometimes to find Clang files.

Merge branch 'master' into greasepencil-object

Geometry Nodes: enable multi-threading in evaluator again

This reverts rB223c6e1ead2940a89465ff66765d16ac14a992b7
because T88598 is resolved now.
