These optimisations should only remove settings that are exactly equal to the parent profile. Support interface settings are an exception, since they were defining non-existing settings in the original profiles. The stand-by temperature is also an exception, since the stand-by temperature of the material profile is set in stone because of firmware.

There have been some problems in the optimization of these profiles, so we undo this for now, preventing people from editing these materials and risking some warnings in Cura's interface, but providing the correct experience for people trying the new materials.
Making these profiles use line distance prevents the user from setting their own density. This density is exactly equivalent.

These are now upgraded to version 3, meaning that they will have to increase their version numbers and remove any start_layers_at_same_position settings they define. None of these profiles define any start_layers_at_same_position so it's just the version number then.
Contributes to issue CURA-3479.
The optimisation script didn't know that the temperature settings in material profiles now refers to default_material_print_temperature rather than material_print_temperature. This caused a few things to go wrong here.
Contributes to issue CURA-3433.
These materials are hard-coded in the optimisation script, so the optimisation script didn't know that those materials were materials and this caused a chain reaction where in the end the profile could only override XML-settings.
