Using "Files" storage for meshes when importing gltf files causes only the first instance of a mesh to reference the mesh file (fixed in master)

Issue description

Using "Files" storage for meshes when importing gltf files causes only the first instance of a mesh to reference the mesh file.
The remaining mesh instances will still have resources pointed at the gltf file.

Steps to reproduce

1. Set up a file with multiple objects referencing the same mesh in Blender.
2. Export to GLTF.
3. Import and set mesh storage to be files.
4. Open new inherited version of gltf and select the different meshes to see what resource they are pointing to.

Does this happen for collada or obj (when loaded a scene instead of mesh mode)

[Arnklit]

The issue appears to be the same on Collada. I don't think you can compare obj as that seems to just output everything as a single simple mesh

[Arnklit]

Tested this in Godot 4 and it's fixed there. I guess the importer is completely different there.
