* 3MF export: a component's bodies as one object with parts (#8139)
file.export and file.save_mesh wrote every body as its own 3MF object and
build item, so a slicer loaded a multi-body part as separate objects and
could arrange them apart on the bed. With objects: "component", each placed
component that holds two or more bodies is written as one object whose
<components> are its bodies' meshes, built once, so PrusaSlicer, OrcaSlicer,
Bambu Studio and Cura load it as one object with a part per body, each of
which can take its own filament. The design's own bodies, and a component
with a single body, stay objects of their own. The default (objects: "body")
writes the same file as before.
- io: model_xml_parts and write_3mf_parts write the parts; export_with_parts
maps body names to them. model_xml_with and export_with_quality give the
same output as before.
- engine: mesh_parts reads `objects` (component is refused for formats
other than 3MF); component_parts groups the placed bodies by placement,
each part named after its occurrence (Bracket:1, Bracket:2).
- file.save_mesh passes the parts on when it also sends the file to a slicer;
file.send_to_slicer's own folder export is unchanged.
Fixes#8139.
