Fix some mesh edition macro operators incorrectly setting an empty description string.

No operator or macro should be missing description. But if they do, then
they should use NULL pointer, and not an empty string.

This behavior was already enforced (through an assert) for operators,
previous commit made it the same for macros.

Cleanup: Remove unused function, unused declaration

Cleanup: Move asset library reference C++ wrapper to own files

Although currently only the asset list code uses the asset library
reference wrapper, it can stand on its own and may be used in more
places in the future. So I prefer to give it its own source & header
file.

Also removed unused includes, added proper namespaces as per our C++
style guidelines, and removed an unnecessary TODO comment.

Compositor: Buffer iterators

Currently we mostly iterate buffer areas using x/y loops or through
utility methods extending from base classes.

To simplify code in simple operations this commit adds wrappers for
specifying buffer areas and their iterators for raw buffers with any
element stride:
- BufferRange: Specifies a range of contiguous buffer elements from a
given element index.
- BufferRangeIterator: Iterates elements in a BufferRange.
- BufferArea: Specifies a rectangle area of elements in a 2D buffer.
- BufferAreaIterator: Iterates elements in a BufferArea.
- BuffersIterator: Simultaneously iterates an area of elements in an
output buffer and any number of input buffers.
- BuffersIteratorBuilder: Helper for building BuffersIterator adding
buffers one by one.
For iterating areas coordinates it adds `XRange` and `YRange` methods
that return `IndexRange`.

Compositor: Export operation results as debug option

When fixing issues, seeing operation results can be helpful for
detecting which operation went wrong.

This commit adds an option for exporting all operations results to
image files.
Exceptions are:
- Output operations: They are already exported or can be seen in UI.
- Constant operations: There are too many and is rarely useful.

They are exported to "<temp session folder>/COM_operations/"
with filenames "<operation class name>_<operation id>.png".
Only works on full frame execution mode.

VSE: Fix multicam splitting all selected strips

`split_multicam` used split operator, where if more strips than
multicam were selected, all would be split, which is undesirable.

Add `Sequence.split()` RNA API function. to split individual strips.
Function accepts `frame` and `split_method arguments`. Returns right
strip after splitting.

In case when strip being split have effects, these will be split too, so
no invalid state should be created.

Selection is not handled, this is by design up to user.

Cleanup: Simplify logic, use C++ types

Also remove an unecessary null check, and make inner loop simpler.

Fix T89624: Vertex painting causes mesh to flicker

The `ibo.lines_paint_mask` extractor doesn't have a callback to iterate
bmesh faces, this made `filter_into` ignore the extractor.

Cleanup: Simplify realizing of pointcloud instances

Just a small change to make the function slightly shorter.

Fix T89868: Crash showing thumbnail of wide-aspect image

Scaling down images could create images with a width or height of zero.

Clamp at 1 to prevent a crash, also add an assert to scaling functions.

Ref D11956

Greatly improve speed of Delaunay when have a lot of holes.

Using part of a patch from Erik Abrahamsson, this replaces the
use of linked lists for original id tracking by Sets.
I had thought that the lists were unlikely to grow to more than
a few elements, but when the mesh has a lot of holes (whose
original ids go *outside* the hole, and therefore, most of the
mesh), this assumption can be very wrong.
On a Text regression test, the time went from 11.67s to 0.16s
with this fix. I also tested to make sure that Boolean didn't
slow down with this, and found it actually had a very slight speedup.

Using Sets exposed a dependency on the ordering of the items
in the id lists, luckily caught by a mesh intersect regression test,
so fixed that.

Fix: Incorrect logic in spline lookup function

This section of code deals with evaluated points,
so that is the size it should use.

Versioning: fix vertex group name loss in linked duplicates.

After rB3b6ee8cee708 by @HooglyBoogly vertex groups were moved
to mesh data, and versioning code was provided to upgrade old
files. However, it fails to consider the case of linked duplicates
having different name lists, and dependent on the object order
can cause some of the names to be lost. This can even be all of
them, if there is a duplicate without any names, which can be
easily created by lazy Python code.

To fix this, change the code to use the longest available name list.
