Write active material metadata to ufp when saving.CURA-8610_save_package_metadata

Add function to fetch package_id using only information from XmlMaterialProfile material container.
The only piece of information associating the material container and the package together is the file_name. To find the package that owns a material we have to search each of the material package paths.

It would be great to find a cleaner solution (preferable one that doesn't require invalidating the cached containers).
