CURA-4451
- Add upgrade script for 3.0. to 3.1
- Upgrade old stack files so they will use "empty_quality" as the
"Not Supported" quality profile.
- Increase SettingVersion to 4
This was delivered false by the materials team. It seems that in the end they decided to not use gradual infill for PP but only made the change in UM3, not UM2+. Removing gradual infill also requires me to set the infill density to 20% (the default).

Note that Git says that Fast was renamed to Verydraft, but in reality Fast was renamed to Draft and Draft was renamed to Verydraft.

These are optimised to the level of the materials: Anything that is common between quality profiles with the same material and nozzle gets bubbled to the profile for that material (per nozzle). It doesn't bubble any further (to the variant) because that could have an impact on the other profiles.
This basically only removes settings because where these settings then bubble to is the material profile in the fdm_materials repository. And a lot of settings are just removed because they are equal to the default.
