Fix duplicated file reloading

Browse Source 
CURA-11905

Instead of using the object name for reloading meshes inside a 3MF file, use a dedicated mesh ID property that is only stored internally, doesn't have to be unique (because the combination filename+ID will be) and can't be changed by the user. This should improve 3MF file reloading, and also fixes reloading of duplicated instances, because multiple meshes can now have the same mesh ID.
