This has come up a couple of times and it seems better to change the
implementation from blender/blender-addons@f1dd37b8ac [which only
exported edge creases when a subd modifier with enabled `Use Creases`
option was present] in a way that these are always exported (if present).
Also took the liberty to rename the variable name for the layer to
correspond to "crease".
Thx @mont29 for handholding on this one!

Geometry Nodes can change the materials of the Object, for Mesh Objects,
the new materials are present in the evaluated Object, but for non-Mesh
Objects, the new materials may not be present until the evaluated Object
has been converted to a Mesh.
This patch fixes the materials in FBX export, with Apply Modifiers
enabled, of non-Mesh types with Geometry Nodes that change materials.
Rather than getting the materials from the evaluated Object, the
materials are now retrieved from the Mesh created from the evaluated
Object.
To support object-linked material slots, the materials on the new Mesh
are replaced at the same indices as the object-linked material slots.

The FBX SDK specifies that normals should use the IndexToDirect FBX
reference mode. This mode allows data written to FBX to be deduplicated
by writing a separate array of indices into the deduplicated array of
data that can be used to reconstruct the full array of data.
When Unity imports per-vertex normals with the IndexToDirect reference
mode, it erroneously considers the imported mesh's normals invalid if
any of its normals were deduplicated. This issue is not present in other
external software that I have tested.
This patch modifies the export of per-vertex normals to not perform any
deduplication, avoiding the issue in Unity's FBX importer while
maintaining use of the IndexToDirect reference mode.
The add-on's patch version has been increased.

The function `rna_def_attributes_common` assumed that the owner of the
attributes is an `ID`. This PR refactors the code to partially remove this
assumption.
The `rna_def_attributes_common` function now takes an argument
`AttributeOwnerType type` that defines what `AttributeGroup` should be used.
This is in preperation for #116043 where we want to use
`rna_def_attributes_common` for grease pencil drawings, which are not IDs.
In addition to the refactor explained above, this also changes the API
slightly:
Previously, the `AttributeGroup` defiend `active_color`,
`active_color_index`, `active_color_name`, `default_color_name`, and
`render_color_index` for all IDs. These properties could only be used by
meshes. So this PR seperates the `AttributeGroup` type into one type
per attribute owner: `AttributeGroupMesh`, `AttributeGroupPointCloud`,
`AttributeGroupCurves`, and `AttributeGroupGreasePencil`.
As such the properties mentioned above are now only usable by meshes.
Note that this technically breaks the API and will have to be noted in the
release notes.

A few files included in reports contained normals that were not normalized.
In order to contain consistent normals around smooth corner fans, sharp
edges are added when neighboring corner normals aren't close enough.
Non-unit-vector normals also triggered this check.
Blender used to do this implicitly when the derived `MeshLoop.normal`
value was set. That API has been changed already, and it's clearer if the
addon provides normalized normals, so this PR adds a normalization
step to the FBX importer.

Disabling the last Subdivision Surface modifier was removed by mistake
in
blender/blender-addons/commit/bc801d7b1dad4be446435e0cab4d3a80e6bb1d04
This patch restores the mistakenly removed code that disables the last
Subdivision Surface modifier when the option to export FBX Subdivision
Surface is enabled.
The add-on's patch version has been increased.
