CURA-3872
We add a new setting "machine_nozzle_type" to give the engine
information about the nozzle type, such as "AA" and "BB". This is
applicable to UM3 and UM3XL.
The UM3 definition sets the setting to 3mm. Nothing else sets it to another value except FDM Printer. I left the UM3 setting in and removed all travel_avoid_distance settings in the UM3 profiles.
These updates bring different speeds for support-top vs. support-bottom, and changes the bottom pattern now that they are separately configurable. I also sorted the BB0.8 variant alphabetically (raft settings were out of place).
Arguably the most important one. This is omitted from the original profiles so the original script assumed it had a nozzle size of 0.4mm.

Otherwise it acts as if the settings were the defaults for FDMPrinter rather than defaulting to the current UM3 settings.

Sample testing confirms that these are equal to their originals. Nylon, PLA and PVA were already optimised, but ABS and CPE weren't. Now all are optimised except some 0.4mm core profiles. I'll see to those next. Note that the filament flow compensation setting is still wrong in these profiles (it was wrong in the original profiles as well).

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.
