It was applying the bounds clamp to each object individually,
which changed spatial relationships between objects. Make the logic
match what used to be done in the Python OBJ importer back in the day.

Change the maximum data-block name from 64 to 256 bytes by increasing MAX_ID_NAME value.
Also increase a few related non-ID data name max size, essentially the action slots identifiers, as these are the primary key used to match an Action's slot to an ID by name.
Other sub-data (bones, modifiers, etc.) lengths are not modified here, as these can be made actual dynamic strings in the future, while keeping (a reasonable level of) forward compatibility, during the course of Blender 5 release cycles.
Implements #137608.

Current NURBS evaluation handles corners or sharp angles poorly. Sharp
edges appear when a knot vector value is repeated `order - 1` times.
Users can make sharp corners by creating NURBS curve with `Bezier` knot
mode or by setting `order` to 2 for legacy curves. The problem occurs
because current algorithm takes all the curve's definition interval,
divides it into equal parts and evaluates at those points, but corners
are exactly on repeated knot's. To hit those, the resolution has to be
increased higher than required for the rest of the curve.
The new algorithm divides non zero length intervals between two adjacent
knots into equal parts. This way corners are hit with a resolution of 1.
This does change the evaluated points of NURBS curves, which is why some
test results have to be updated in this commit.

- #122256: Clamp Size option did not work at all, due to mesh
bounding box still not being calculated (and was firing an assert
in Debug build).
- #123862: Clamp Size option was rounding the resulting scale to
powers of ten, which is not what anyone would expect.
This fixes both issues, and adds test coverage.

Reworks the implementation for how knots are interpreted when importing
NURBS in .obj format. It refactors each test into a separate function
and simplifies functions using a 'multiplicity sequence' which counts
repeated occurances of knot values (or their 'multiplicity'). Making
comparisons simpler, clearer, and with improved correctness.
With regard to regression tests behavior is almost the same, noticable
difference is consideration of cyclic. Allowing curves with multiplicity
at the endpoints to be cyclic (so Bezier curves can be cyclic given
one repeated point). Untested behavior may also have been 'refined'
(changed), but additional tests would be needed to identify those cases.

This change moves the tests data files and publish folder of assets
repository to the main blender.git repository as LFS files.
The goal of this change is to eliminate toil of modifying tests,
cherry-picking changes to LFS branches, adding tests as part of a
PR which brings new features or fixes.
More detailed explanation and conversation can be found in the
design task.
